3.0 NARRATIVE SUMMARY OF STORMWATER PROGRAM ACTIVITIES

The 2010 MS4 Permit requires the City of Mesa (City) to provide a narrative describing the implementation, progress, and challenges associated with the stormwater program activities as provided in the following subsections. The permit also requires the City to explain any significant developments or changes to the number or type of activities or the priorities or procedures for specific management practices. 3.1 PUBLIC EDUCATION & OUTREACH The 2010 MS4 Permit requires the City to report outreach events, topics, number of people reached, number and type of materials distributed and the target groups in this Annual Report as it pertains to the City’s stormwater public education and outreach program. The City’s stormwater public education and outreach method is managed through the STormwater Outreach for Regional Municipality (STORM) organization. STORM is comprised of Phase I and Phase II MS4 operators in the greater Phoenix Metropolitan Area. STORM was founded in 2002 largely in response to the Phase II stormwater regulations and was spearheaded by the Phase I MS4 operators as a method of assisting all regulated MS4 operators in the development of their public education programs, among other things. As such, the City played a key role in the early years of the development of the STORM organization and continues to be a major participant and proud supporter to this day. The traditional approach to public stormwater education and outreach is for individual communities to work independently. STORM encourages a new perspective at a regional level to improve public outreach and education. Members meet monthly to discuss ideas, gather information, and share results of stormwater management tools, techniques, programs, and initiatives. The City realizes a great economic benefit from their membership investment. For a relatively small contribution, the City receives a significant return in public outreach and education, much more than the City would have gained working independently. Membership in STORM also provides increased buying power that helps achieve bulk pricing on storm water pollution awareness promotional items. Additionally, the ability to


cooperatively apply for grants and other financial assistance helps further the common goal of public education to reduce stormwater pollutants and ultimately improve the regional water quality. STORM uses a multimedia approach targeting audiences through radio, television, special events, and providing permit information to the general public and the regulated community. These approaches include, but are not limited to, radio and television public service announcements (PSAs), developing brochures and other handouts, and attending public events. Additionally, STORM has created a comprehensive website that includes the copies of outreach materials and PSAs which can be accessed at www.azstorm.org. 3.1.1 General Public The 2010 MS4 Permit requires the City to target at least one of the following groups during each permit year (August 30 through August 29th):

1. General Public 2. Residential Community 3. Home Owners 4. Home Owners Associations 5. Schools

The 2010 MS4 Permit requires that at least one of the following topics be addressed for these target groups:

• Post-construction ordinances and long-term maintenance requirements for permanent stormwater controls

• Stormwater runoff issues and residential stormwater management practices • Potential water quality impacts of application of pesticides, herbicides and

fertilizer and control measures to minimize runoff of pollutants in stormwater • Potential impacts of animal waste on water quality and the need to clean up and

properly dispose of pet waste to minimize runoff of pollutants in stormwater • Illicit discharges and illegal dumping, proper management of non-stormwater

discharges, and to provide information on reporting spills, dumping, and illicit discharges

http://www.azstorm.org/


• Spill prevention, proper handling and disposal of toxic and hazardous materials, and measures to contain and minimize discharges to the storm sewer system

• Installation of catch basin markers or stenciling of storm sewer inlets to minimize illicit discharges and illegal dumping to the storm sewer system

• Proper management and disposal of used oil STORM aired a PSA campaign targeting swimming pool discharges. The PSA aired in both English and Spanish on eight radio stations, ran from June 3 through June 30, 2013 and reached over 3.2 million people. The campaign included 134 (30 second) paid spots; plus 82 (30 second), 4 (15 second) and 6 (10 second) "bonus" spots at no charge. A Community Service interview was aired on one of the participating stations. The cost of the campaign was $5,021.65. 3.1.2 Business Sectors The 2010 MS4 Permit also requires the City to target at least one of the following business sector groups during each permit year:

1. Development Community 2. Construction Site Operators 3. Targeted Sources 4. Types of Businesses (industrial or commercial)

The 2010 MS4 Permit requires that at least one of the following topics be addressed for these target groups:

• Planning ordinances, engineering standards and grading and drainage design standards for stormwater management in new developments and significant redevelopments

• Municipal stormwater requirements and stormwater management practices for construction sites

• Illicit discharges and proper management of non-stormwater discharges • Spill prevention, proper handling of toxic and hazardous materials, and measures

to contain and minimize discharges to the storm sewer system


• Proper management and disposal of used oil and other hazardous or toxic materials, including practices to minimize exposure of materials/wastes to rainfall and minimize contamination of stormwater runoff

• Stormwater management practices, pollution prevention plans, and facility maintenance procedures

STORM was a sponsor of the Low-Impact Development (LID) Basics and Beyond: Low Impact Development Trends in the Southwest workshop on February 5, 2013. STORM contributed $1,000 to the ASU Sustainable Cities Network for costs associated with the workshop. Approximately 122 were in attendance at the workshop. Workshop details and presentations are posted at the following website address. http://sustainablecities.asu.edu/2012/12/10/lid-basics-and-beyond-low-impact-development-trends-in-the-southwest/ STORM also targeted operators of industrial facilities that were required to have coverage under the ADEQ Multi-Sector General Permit by hosting the 2013 Industrial Stormwater Compliance Made Easy seminar. The seminar drew an audience of approximately 84 attendees and featured presentations by representatives of consultant representing member municipalities and the ADEQ. The Arizona Department of Transportation, a STORM member, provided the seminar room at no charge. STORM expended $1,177.18 for costs associated with printing, mailing, and refreshments. Seminar presentations are available at the following website address. http://www.azstorm.org/construction-seminar/maricopa-county-stormwater-construction-seminar 3.1.3 Additional Education & Outreach Activities More information regarding the STORM organization’s public education and outreach program activities for the current reporting year can be found in the STORM Annual Report, FY 2011 available at the following address: http://www.azstorm.org/annual-reports. 3.2 PUBLIC INVOLVEMENT The 2010 MS4 Permit requires the City to identify activities, number of people involved, number and type of materials distributed, if applicable and to describe MS4 system for

public reporting of spills, dumping, discharges, and related stormwater issues in this Annual Report as it pertains to the City’s public involvement stormwater program. 3.2.1 Environmental Hotline The 2010 MS4 Permit requires the City to provide and publicize a reporting system to facilitate and track public reporting of spills, discharges or dumping to the storm sewer system (i.e., storm water hotline, web page, etc.) on a continuous basis. The City established an Environmental Hotline as a method to receive calls regarding stormwater as well as other environmental issues [air quality, hazardous material disposal, illegal dumping, and public nuisances (i.e. mosquitoes)]. During normal business hours, calls are answered by personnel trained to understand the nature of the types of calls they receive and can address questions that are informational in nature. Where a complaint is filed, the record is turned over to appropriate personnel trained in code enforcement procedures for inspection. All complaints are logged into the City’s Tidemark® database system for tracking purposes. During off-business hours, callers are provided an opportunity to leave a message which is retrieved and processed the following business day. Emergency calls related to stormwater issues received during off-hour operations are handled through the City’s public safety dispatch operations. 3.2.2 Stormwater Website The City maintains a website specifically for stormwater. That website has information specific to the City’s stormwater program. The 2010 MS4 Permit requires the City to post the Storm Water Management Plan (SWMP) and latest annual report on the City’s web site within one (1) year from the effective date of the permit. The draft version of the SWMP was posted on the City’s website within ten (10) business day of the end of the first permit term (August 30, 2011). The final version of the SWMP, after being approved of by the ADEQ, was uploaded to the website within ten (10) business days after the receipt of the ADEQ approval (date April 12, 2012). The City will also provide a link to this Annual Report within ten (10) business days of submittal of this document to the ADEQ. These documents are accessible through City’s Environmental & Sustainability Division website at http://www.mesaaz.gov/environ/.

http://www.mesaaz.gov/environ/


3.2.3 Household Hazardous Waste Program The 2010 MS4 Permit requires the City to incorporate at least one of the following as fundamental support to its storm water program:

• An opportunity to involve the public in the City’s stormwater program and encourage public participation in monitoring and reporting spills, discharges, or dumping within their communities (such as facilitation of neighborhood watch groups) once per year.

• An opportunity to participate in the City’s stormwater program, such as voluntary litter control activities (e.g., facilitation of Adopt-A-Wash, Adopt-A-Park, and Adopt-A-Street litter control activities) or voluntary erosion control projects as a regular ongoing activity.

• A household hazardous waste (HHW) program to facilitate proper disposal of used oil, antifreeze, pesticides, herbicides, paints, and other hazardous and toxic materials by city residents (such as scheduled household hazardous waste collection events or operation of full-time disposal facilities) a minimum of two (2) times per year for the first two (2) years of the permit, three (3) times per year for years three (3) and four (4) of the permit, and every year thereafter.

The City has selected to incorporate the HHW program into their stormwater program since the City has been conducting these types of events as part of meeting the requirements of their previous MS4 permit. The City’s HHW program facilitates proper disposal of used oil, antifreeze, pesticides, herbicides, paints, and other hazardous and toxic materials as well as electronics, tires, and prescription medicine generated by city residents. During this reporting period, the City provided four opportunities to residents to dispose of HHW. By providing a proper disposal option to the City’s residents, the City has kept this material from potentially being illegally dumped into the MS4, spilled onto City streets, or improperly disposed of into solid waste receptacles. The City’s HHW collection events are held at two different locations, one on the east side of the City, the other on the west. The events alternate between locations to ensure that all residents have adequate access to these events. Information, including


the number of residents attending, amount and type of material received, is included as an attachment to this Annual Report (see Section 13.7 and Attachment C). At these events, the City distributes packets to residents as they enter. Based on the timing of each event, this information would have included some or all of the following:

• HHW Collection Event Date Flier • Additional Electronics Recycling Opportunities • Christmas tree recycling information • Environmental & Sustainability Information

3.3 NON-STORMWATER FLOWS TO THE CITY’S MS4 The City’s 2010 MS4 Permit requires the City to summarize their program activities related to non-stormwater flows. This includes:

1. Prevention activities associated with the release of non-stormwater flows to the MS4;

2. Training dates and topics of City personnel addressing non-stormwater flow complaints; and,

3. Overview of identified sources resulting from industrial facility inspections, illicit releases, types of illicit connections identified, and significant corrective or enforcement actions.

For the overview of industrial facility inspections, see Section 3.6.2. 3.3.1 Non-Stormwater Flow Prevention Activities The City does not operate as a permitting agency for stormwater or non-stormwater flows. However, the City has identified the following non-stormwater releases to target through the development of fact sheets to reduce the pollutants from these sources to the maximum extent practicable.

Targeted Release Targeted Pollutant(s) Targeted Areas Flood Irrigation Water Sediment Irrigation over areas that are

exposed to bare soils.


Targeted Release Targeted Pollutant(s) Targeted Areas Individual Car Washing Sediment

Solvents

Washing heavily soiled trucks. Washing undercarriage or engine compartments.

Street Wash Water Sediment Oils

Washing paved surfaces impacted with dirt. Washing standing liquid oil spills from paved surfaces.

Swimming Pools & Hot Tub Water (generally not allowed)

Chlorine Bromine Sediment Bacteria

Flows must remain on site (irrigation usage) go to sanitary sewer, or be pumped and hauled away for disposal.

During this reporting period, the City finalized these documents which are accessible through City’s Environmental & Sustainability Division website at http://www.mesaaz.gov/environ/. 3.3.2 Training Dates and Topics The City developed an Environmental Program Training Standard Operating Procedures manual (dated February 2012) to meet the training requirements of the 2010 MS4 Permit and other environmental program areas. Previously, a training module was developed targeting inspectors/staff with no direct stormwater responsibilities (general awareness training). Topics included what types of discharges are allowed under the Title 8, Chapter 5 of the Mesa City Code (Stormwater Code) and the procedure for reporting suspected illicit discharges. During this reporting period, a training module was developed targeting stormwater inspectors/field staff (enforcement training). Topics include identifying illicit discharges, tracking illicit discharges, allowable stormwater discharges, and enforcement actions. 3.3.3 Investigations For stormwater complaints publically reported to the City, the 2010 MS4 Permit requires the City to:

1. Investigate reported releases to identify the source(s) of the release;

http://www.mesaaz.gov/environ/


2. Respond to 90% of all reports of releases made to the City (i.e. called into the Environmental Hotline, or other form of reporting) or other detection methods (i.e. pro-active inspections); and,

3. Initiate investigation of 80% of releases reported to the City within three (3) business days of the date of report.

The City has established an Environmental Hotline as a method to receive calls regarding stormwater as well as other environmental issues (see Section 3.2.1). It has been the City’s experience that non-stormwater releases reported to the Environmental Hotline are identified at locations prior to entering the subsurface portions of the City’s storm sewer system (primarily flowing down the curb and gutter system). Most connections that are reported to the Environmental Hotline are in the form of a pipe (usually PVC) installed through a block wall or a pump hose that is placed in the yard, through a fence, or directly in the street or alleyway. These surface flows and connections are generally easy to track down to the source through a drainage area investigative approach. In general, the City can utilize a corrective or enforcement action to obtain compliance with the Mesa City Code. “Corrective actions” are generally those taken by the responsible party to remove pollutants or reduce the potential of pollutants from entering the City’s MS4. “Enforcement actions” are those taken by the City to address any hazards associated with the violation, generally where a voluntary compliance option has failed to be an effective tool in gaining compliance, and includes reporting violations to other City departments or regulatory agencies having ultimate authority regarding the nature of the violation. During this reporting period, the majority of the complaints received through public reporting involved draining and/or backwashing of swimming pools to the City’s storm sewer system. Other noted complaints involved debris in drainage channel, oil in the street, grey water, vegetation blocking drainage, and track-out from a yard.


Section 8-5-5 of the City’s Stormwater Code (Commencement of Action) provides for formal enforcement actions by issuing a notice of abatement under this Chapter or a citation for civil sanctions under this Chapter, or both. However, the code provides that City employees may seek voluntary compliance through notices of violation, warnings, or other informal devices designed to achieve compliance in the most efficient and effective manner under the circumstances. The City’s code enforcement procedure provides the option of voluntary compliance to responsible parties to implement corrective actions by issuing a courtesy notice. Where voluntary compliance is not obtained within a reasonable timeframe, the City has the ability to issue a civil violation and citation, issue a notice to abate, or suspend any license issued by the City. Additionally, the City may impose criminal violations for responsible parties identified as habitual offenders. Most cases were closed with the issuance of a courtesy notice during this reporting period. 3.4 MUNICIPAL FACILITIES The 2010 MS4 Permit requires the City to report the following in the annual report as it relates to City facilities:

1. Description of the status of identification and inventory of these facilities. 2. Overview of inspection findings (i.e., number inspected, number with follow-up

actions needed, significant findings). 3. Description of activities needed and performed in response to inspections

(control measures implemented). 4. Description of the identification and tracking of municipally-owned and operated

facilities subject to permitting under the Multi-Sector General Permit (MSGP). In general, this program includes City facilities that meet the following conditions:

• City parks, golf courses, and other recreational facilities (where landscape maintenance, herbicide, pesticide, and fertilizer application, and waste management are implemented);

• Public swimming pools (pool maintenance/repair and chemical storage); • Water treatment plants; • Public septic systems (sanitary waste handling);


• Fire stations and other city fleet maintenance facilities (vehicle washing and maintenance, chemical handling, waste storage);

• Publically-owned treatment works and sludge handling areas; • Material and waste storage and processing facilities, including oil collection

facilities; or, • Those facilities that handle, store, or otherwise use hazardous materials where

any single container exceeds five (5) gallons and where such materials are exposed or have the potential to be exposed to stormwater

3.4.1 Description & Status of Inventory The City deleted two facilities from its inventory during this reporting year. One facility was rented to a tenant and the City has no operations taking place at that facility, the other was demolished. 3.4.2 Overview of Findings The facility inspection extended beyond stormwater issues. Most findings included identifying hazardous waste that needed to be disposed of, where these wastes were not exposed to stormwater. Other issues were unlabeled containers, necessity for fire cabinets, buckets of chemicals next to sanitary sewer without secondary containment, etc. Three facilities were identified that stored over 5 gallons of hazardous materials. One facility was noted as having a 55-gallon contaminated fuel drum that was exposed to stormwater. The other two facilities stored over 250 pounds of chlorine gas but these were stored under a shelter. 3.4.3 Response Actions The City is evaluating options regarding the facility with the 55-gallon drum of contaminated fuel. This facility will be re-inspected this reporting period to identify any additional issues and to resolve the location of the 55-gallon drum. If the drum cannot be moved indoors or otherwise put under a shelter, a spill plan will be developed for this facility. The chlorine gas canisters do not pose a threat to stormwater quality regardless of their storage location, so no response action is expected for those facilities.


3.4.4 Facilities Covered under the Multi-Sector General Permit The City has one facility that is covered under the Multi-Sector General Permit. 3.5 INVENTORIES, MAPS, AND MAP STUDIES The 2010 MS4 Permit requires the City to report the status of all inventories, maps, and map studies required by the permit to be developed including completion dates. 3.5.1 Inventories The 2010 MS4 Permit requires to City to develop “inventories” or other methods of identification of the following:

1. An inventory or map of all major outfalls, and of other field screening points (if applicable), identified by Mesa as priority for illicit discharges or other non-stormwater flows (see Section 13.2);

2. An inventory, list, database or map of facilities owned and operated by Mesa (excluding office and administration buildings) that have the potential to discharge pollutants to waters of the United States (see Section 13.8 and Attachment D);

3. An inventory, list, or database of private commercial and industrial facilities that have the potential to discharge pollutants to the city’s storm sewer system (see Section 3.6.1); and,

4. An inventory, list, database, or map of construction activities that result in land disturbance of one (1) or more acres and that have the potential to discharge to the city’s storm sewer system (see Section 3.7.1).

3.5.2 Maps Appendix A of the 2010 MS4 Permit requires the City to prepare and routinely update maps of the MS4 system that incorporates mapping of all of the following:

1. Linear Drainage Structures - Line layer showing the location of the City’s MS4 storm drain pipes and the direction of stormwater flow.

2. Storm Drain Inlets and Catch Basins - Point layer showing the locations of the City’s MS4 storm drain inlets and catch basins.

3. Major Outfalls, Field Screening Points, and Monitoring Locations


a. Point layer showing the location of the City’s stormwater monitoring locations, field screening points, and major outfalls (pipes or culverts).

b. Layer showing the drainage area associated with each monitoring location identified in the 2010 MS4 Permit.

4. Detention/Retention Basins - Point or polygon layer showing the locations of all City-owned retention and detention basins that are connected to the municipal stormwater conveyance system (i.e., that receive drainage from or discharge to a stormwater conveyance).

5. Jurisdictional MS4 Boundary - Line or polygon layer showing the jurisdictional boundaries of the City’s MS4, including any new land annexations during the permit term.

The City is required to incorporate mapping of the above by the due date of the fourth (4th) year annual report (i.e. September 30, 2014). The City maintains Land and Utilities maps that are continually updated for use by City employees. The application provides the ability to view and print Land, Water, Gas, Sewer, or Storm Drain maps for each quarter section of the City. The City also maintains this information in ArcGIS software which is available for use by select City personnel. As of the date of the Annual Report, the City’s current mapping system includes all the information that is required under the 2010MS4 Permit. 3.5.3 Map Studies Appendix A of the 2010 MS4 Permit requires the City to complete a study that evaluates the cost, method, and time it will take to complete the following:

1. Linear Drainage Structures a. Line layer showing the location of all streets used for stormwater conveyance

and the direction of stormwater flow. b. Line layer showing other linear stormwater conveyance structures (channels,

floodways, etc.) and the direction of stormwater flow. 2. Land Uses - Layer showing the land uses. 3. Detention/Retention Basins

a. Point or polygon layer showing the location of all privately-owned retention and detention basins that are connected to the municipal stormwater


conveyance system (i.e., that receive drainage from or discharge to a stormwater conveyance).

b. Line layers showing the drainage infrastructure associated with each retention/detention basin.

4. Locations of Discharges to Waters of the United States - Line or polygon layer showing the location (and name) of all waters of the United States that may receive stormwater discharges from the MS4 and to clearly identify any listed Outstanding Arizona Water or Impaired Water.

The City is required to complete studies associated with the above mapping requirements by the due date of the fourth (4th) year annual report (i.e. September 30, 2014). As of the date of the Annual Report, the City’s mapping system includes all of the information required in the mapping studies having completed a study to determine the direction of flow from the streets with storm water conveyance. Please note, the City does not discharge to waters of the United States that are considered to be an Outstanding Arizona Water or Impaired Water. 3.6 INDUSTRIAL FACILITIES The 2010 MS4 Permit requires the City to report the following in the Annual Report as it pertains to the inspection of private commercial and industrial facilities:

1. Status of identification and inventory of these facilities. 2. An overview of inspection findings and note significant findings. 3. Corrective and enforcement actions needed and taken in response to

inspections. 3.6.1 Identification and Inventory of Private Commercial and Industrial Facilities The 2010 MS4 Permit requires the City to:

1. Develop and maintain an inventory, list, or database of commercial and industrial facilities that have the potential to discharge pollutants to the City’s MS4.

2. Maintain a system to collect and update this information on a routine basis.


3.6.1.1 Commercial Facilities The City inspects commercial facilities that require a grease removal device (GRD) as part of the City’s industrial pre-treatment fats, oils, and greases (FOG) program. These types of facilities are required to submit an industrial pretreatment survey to the City to determine the type of business (i.e. industrial, commercial, manufacturing, restaurant etc.) and the nature of the facilities discharges to the City’s sanitary sewer. This survey assists the City in determining what, if any, pretreatment devices are required. These facilities are entered into a database and tracked for inspection purposes. During these inspections, City inspectors also conduct a stormwater assessment associated with the operations of these facilities. 3.6.1.2 Industrial Facilities The City contracted InfoUSA, a private customer listing group commonly used by other regulated Phase I MS4 operators (i.e. City of Phoenix, City of Tempe), to provide information on facilities subject to the MSGP based on standard industrial classification (SIC) codes. Additionally, the City conducted a review of the United State Environmental Protection Agency Toxic Release Inventory (TRI) database. The City redeveloped their Industrial (Private) database to include new information supplied by InfoUSA and to incorporate the most recent listing of TRI facilities. This information increased the City’s industrial facility database to over 750 facilities. The inventory at the end of this reporting period was 719 facilities. Since the development of the database, some facilities have been identified and added to the inventory, but others were removed from the inventory because they went out of business, the information supplied by InfoUSA improperly identified them as operating in the City of Mesa (i.e. the address provided was outside of the City’s incorporated area), or name of the company changed (in these cases the old business name record was deleted from the inventory and a new record was created for the new business name). 3.6.2 Overview of Inspection Findings and Significant Findings The 2010 MS4 Permit requires the City to:

1. Develop an inspection and prioritization program.


2. Inspect at least 50 industrial facilities [Superfund Amendments and Reauthorization Act (SARA) Title III and MSGP facilities] each year during the permit term.

3. Inspect other commercial and industrial sources (or category of sources) which the City determines to be a significant source of pollutants.

4. Verify implementation and maintenance of stormwater management practices in compliance with the City’s Stormwater Code.

5. Identify and eliminate potential discharges of pollutants to the system. 6. Confirm permit coverage to discharge stormwater associated with industrial

activity, as applicable. 7. Conduct follow-up inspections as necessary.

3.6.2.1 Commercial Facilities Inspection & Prioritization Inspections of commercial facilities are based on a geographical distributional approach. Commercial inspections are also conducted in response to complaints from other City staff and the general public. Priority is given to complaint responses, which are investigated without regard to the geographical distribution approach. Commercial inspections are conducted by City inspectors trained to identify stormwater compliance issues related to these types of facilities. Though all commercial facilities inspected under the FOG program are assessed for stormwater compliance, those that pose a higher risk include, but are not limited to:

• Auto Repair Shops; • Gasoline Stations; • Grocery Stores; • Restaurants; • Car Washes; and, • Movie Theaters

Stormwater issues that were identified as a result of follow-up inspections at commercial facilities during this reporting period included:

• Discharges from wash bays; and, • Used oil exposed to stormwater.


3.6.2.2 Industrial Facilities Inspection & Prioritization The following criteria are used to determine categories and establishing a prioritization for conducting industrial inspections.

1. Complaints. 2. Newly identified TRI listed facilities that have not been previously inspected. 3. Current TRI listed facilities that were not previously inspected within the last 5

years. 4. Industrial facility sectors, SICs or North American Industry Classification System

(NAICS) groups that have a reasonable potential to conduct dust generating operations and that may require permit coverage for such operations (i.e. unlikely to be no-exposure facilities).

5. Other industrial facility sectors, SICs or NAICS groups that the City determines may be a significant source of pollutants.

During this reporting period, the City concentrated on industrial facilities involved in the following operations (also provided are the industrial subsector code):

• Medicinal Chemicals and Botanical Products; Pharmaceutical Preparations; in vitro and in vivo Diagnostic Substances; and Biological Products, Except Diagnostic Substances (C5)

• Paints, Varnishes, Lacquers, Enamels, and Allied Products (C5) • Concrete, Gypsum, and Plaster Products (E2) • Steel Works, Blast Furnaces, and Rolling and Finishing Mills (F1) • Dimension Stone (J2) • Crushed and Broken Stone, Including Rip Rap (J2) • Nonmetallic Minerals Services, Except Fuels (J2) • Miscellaneous Nonmetallic Minerals, Except Fuels (J2) • Automobile Salvage Yards (M1) • Scrap Recycling and Waste Recycling Facilities except Source-Separated

Recycling (N1) • Source-separated Recycling Facility (N2) • Fabricated Metal Products, Except Machinery and Transportation Equipment,

and Coating, Engraving, and Allied Services (AA1)


• Jewelry, Silverware, and Plated Ware (AA1) • Fabricated Metal Coating and Engraving (AA2) • Industrial and Commercial Machinery, Except Computer and Office Equipment

(AB1) • Transportation Equipment Except Ship and Boat Building and Repairing (AB1)

Many of the industrial facilities in the City’s database that were inspected during this reporting period did not perform operations consistent with the SIC codes that were assigned to them from the information provided by InfoUSA. When contacted, the facilities operator was asked what types of operations took place there and assisted them with identifying the appropriate SIC. The City conducted an inspection to ensure that these facilities did not require MSGP coverage and that their operations were being performed in compliance with the City’s Stormwater Code. The City’s industrial inspection database was updated for revised SIC codes. Issues at industrial facilities noted as part of the inspection process during this reporting period included:

• Open containers of oil/water exposed to stormwater; • General housekeeping issues; • Paint storage in uncovered area; • Water in loading dock; • Accumulation of old tires; • Process water and trash discharged to drywell; and, • Exposed dry sludge area.

3.6.3 Summary of Corrective and Enforcement Actions The 2010 MS4 Permit requires the City to:

1. Establish an effective compliance and enforcement program that incorporates escalating actions for violations of the City’s Stormwater Code that provides timeframes and escalation for corrective actions; and,

2. Focus the escalated enforcement protocol on having the highest level of enforcement action resolved within one (1) year of the initial inspection/violation.


In general, the City can utilize corrective or enforcement actions to obtain compliance with City’s Stormwater Code (see Section 3.3.3). 3.6.3.1 Commercial Facility Corrective & Enforcement Actions Corrective actions needed and taken at commercial facilities during this reporting period included:

• Discharges from a wash bay flowing into an on-site retention basins • Used oil stored in an area exposed to stormwater

Section 8-5-5 (Commencement of Action) of the City’s Stormwater Code provides for formal enforcement actions by issuing a notice of abatement or a citation for civil sanctions, or both. However, the code provides that City employees may seek voluntary compliance through notices of violation, warnings, or other informal devices designed to achieve compliance in the most efficient and effective manner under the circumstances. The City’s commercial and industrial facility enforcement procedure provides the option of voluntary compliance to responsible parties to implement corrective actions by issuing a courtesy notice. Where voluntary compliance is not obtained within a reasonable timeframe, the City has the ability to issue a civil violation and citation, issue a notice to abate, or suspend any license issued by the City. Additionally, the City may impose criminal violations for responsible parties identified as habitual offenders. Most cases were closed with the issuance of a courtesy notice during this reporting period. During this reporting period, no enforcement actions were needed or taken as a result of stormwater inspections conducted by the City of private commercial facilities. Some cases were closed without a violation being confirmed. The remaining cases were closed when the issue had been addressed or upon the issuance of a courtesy notice. 3.6.3.2 Industrial Facility Corrective & Enforcement Actions Corrective actions needed and taken at industrial facilities during this reporting period included:


• Open containers of oil and oil/water were removed. • Paint was moved under a covered structure. • Water was drained for loading dock. • Old tires were removed. • Reported drywell violations to ADEQ Aquifer Protection Permit (APP) Program

personnel. Section 8-5-5 of the City’s Stormwater Code provides for formal enforcement actions by issuing a notice of abatement or a citation for civil sanctions under the code, or both. However, the code provides that City employees may seek voluntary compliance through notices of violation, warnings, or other informal devices designed to achieve compliance in the most efficient and effective manner under the circumstances. The City’s commercial and industrial facility enforcement procedure provides the option of voluntary compliance to responsible parties to implement corrective actions by issuing a courtesy notice.

During this reporting period, no formal enforcement actions were needed or taken as a result of stormwater inspections conducted by the City of private industrial facilities. Some cases were closed without a violation being confirmed. The remaining cases were closed when the issue had been addressed or upon the issuance of a courtesy notice. 3.7 CONSTRUCTION PROGRAM ACTIVITIES The 2010 MS4 Permit requires the City to report the following in the Annual Report as it pertains to the review of plans and inspections of construction operations:

1. Status of inventory/plan review of these facilities. 2. An overview of inspection findings and significant findings. 3. Corrective and enforcement actions needed and taken in response to

inspections.


3.7.1 Status of Inventory and Plan Review of Construction Operations The 2010 MS4 Permit requires the City to:

1. Develop an inventory, list, or database, or map of construction activities that result in land disturbance of one (1) or more acres and that have the potential to discharge to the City’s storm sewer system within one (1) year of permit issuance (August 30, 2011) and to be updated at least annually;

2. Review at least 80% of plans for new development and redevelopment (such as grading and drainage plans) to verify conformance with the City requirements for stormwater, including erosion and sediment control, prior to issuing construction approvals or authorizations; and,

3. Require a copy of the ADEQ’s Authorization Certificate for non-municipal construction projects (as required by municipal stormwater requirements or ordinances or state stormwater requirements) be submitted prior to issuing construction approval or authorization.

3.7.1.1 Private Construction Projects When plans are submitted to the City, information on the construction project is entered into a database providing a detailed record of the construction operations from the point of plan submittal through inspection and approval (i.e. issuance of a Certificate of Completion or Certificate of Occupancy). The City reviews all construction plans for compliance with all aspects of the City’s Engineering and Design Standards Manual and the City Mesa Code. Stormwater drainage and infrastructure are generally detailed in grading and drainage plans. Approval of these plans is required before a building permit is issued by the City. A copy of the contractor’s ADEQ Authorization Certificate is also required before a building permit is issued by the City of Mesa for projects involving land disturbance of one or more acres. The City places a “hold” that prevents the issuance of a building permit where an ADEQ Authorization Certificate is required until it has been submitted. 3.7.1.2 City Projects For City projects, the City is deeply involved in the project through all phases of development (i.e. conception, planning, construction, and completion). Grading and drainage plans are required for most engineering projects, certainly any project that


disturbs one or more acres of land. The City maintains a separate database for City construction projects that disturb more than 0.1 acres. This is the threshold disturbance limit where a dust control permit would be required from the Maricopa County Air Quality Department. The general contractor is required to submit a copy of their SWPPP for review and approval along with a copy of their ADEQ Authorization Certificate before the contractor is authorized to conduct any land disturbance activities for City projects that disturb one or more acres of land. The City files as a co-permittee under the ADEQ’s Construction General Permit (CGP) and is issued a separate Authorization Certificate. 3.7.2 Overview of Inspection Findings and Significant Findings The 2010 MS4 Permit requires the City to:

1. Establish a prioritization schedule for inspecting construction sites with a higher frequency of inspections for those sites that have a higher potential to discharge to the storm sewer system;

2. Routinely inspect construction projects to determine whether effective erosion and sediment controls are in place, and verify conformance with local stormwater requirements and approved construction plans;

3. Inspect higher priority sites, based on the prioritization schedule, a minimum of one (1) time every three (3) months and all other sites at least once every six (6) months until final stabilization is established; and,

4. Conduct follow-up inspection of construction sites within 30 days to ensure stormwater deficiencies/concerns/non-compliance identified as a result of a routine inspection were corrected

3.7.2.1 Private Construction Projects The City will generally first inspect a private construction operation during the footing stage of development. During this visit, City staff takes time to review the operator’s plans to identify active areas and stormwater best management practices (BMPs). During the inspection of the footing structure(s), City staff look at all active areas of the construction project to ensure that BMPs identified on the operator’s plans are in place and maintained, and to ensure that the only non-stormwater releases to the City MS4


are properly permitted. These projects are inspected thereafter a minimum of one (1) time every three (3) months where construction activities are still active. Where deficiencies are noted and a re-inspection is required, the City will conduct this follow-up inspection within 30 calendar days. Inspection findings for private construction projects during this reporting period included:

• Catch basin inlet protection required. 3.7.2.2 City Projects The City generally conducts a compliance audit within two weeks of the issuance of approval by the City to the general contractor (i.e. issuance of a Notice to Proceed) and where the disturbance of land associated with the project has begun. These projects are inspected thereafter a minimum of one (1) time every three (3) months. Where deficiencies are noted and a re-inspection is required, the City will conduct this follow-up inspection within 30 calendar days. Inspection findings for City construction projects during this reporting period included:

• BMP maintenance; • Lack of perimeter control; • Unprotected catch basins; • Lack of updated SWPPP site inspection records • Illegal Non-stormwater discharges from sites • Lack of erosion control BMPs on stockpiles (i.e. wattles not installed/staked)

3.7.3 Summary of Corrective and Enforcement Actions The 2010 MS4 Permit requires the City to:

1. Establish an effective compliance and enforcement program that incorporates escalating actions for violations of the City’s Stormwater Code that provides timeframes and escalation for corrective actions; and,

2. Focus the escalated enforcement protocol on having the highest level of enforcement action resolved within one (1) year of the initial inspection/violation.


In general, the City can utilize corrective or enforcement actions to obtain compliance with Mesa City Code (see Section 3.3.3). 3.7.3.1 Private Construction Projects Corrective actions needed and taken at private construction projects during this reporting period included:

• Follow up inspection reported site in compliance. Section 8-5-5 of the City’s Stormwater Code provides for formal enforcement actions by issuing a notice of abatement or a citation for civil sanctions under this Chapter, or both. However, the code provides that City employees may seek voluntary compliance through notices of violation, warnings, or other informal devices designed to achieve compliance in the most efficient and effective manner under the circumstances. The City’s private construction enforcement procedure provides an option of obtaining voluntary compliance by allowing a reasonable timeframe for obtaining compliance and taking actions equivalent to issuing a stop work order (i.e. not approving site improvements until such time the issues have been adequately addressed) where necessary. Where voluntary compliance is not obtained within a reasonable timeframe, the City has the ability to take formal enforcement actions by issuing a civil violation and citation, issue a notice to abate, or suspend any license issued by the City. Additionally, the City may impose criminal violations for responsible parties identified as habitual offenders. 3.7.3.2 City Projects Corrective actions needed and taken at City construction projects during this reporting period included:

• BMP maintenance needs were addressed; • Perimeter control was established; • Catch basins BMPs were installed; • Updated SWPPP inspection records were available • Discharge source removed/relocated to another portion of site • Erosion control BMPs installed on stockpiles


Section 8-5-5 of the City’s Stormwater Code provides for formal enforcement actions by issuing a notice of abatement or a citation for civil sanctions under this Chapter, or both. However, the code provides that City employees may seek voluntary compliance through notices of violation, warnings, or other informal devices designed to achieve compliance in the most efficient and effective manner under the circumstances. The City construction enforcement procedure provides for an option of obtaining voluntary compliance by allowing a reasonable timeframe for obtaining compliance and confirming during a follow-up inspection(s), and where compliance issues remain unresolved, initiating the stop work order process until such time the issues have been adequately addressed. 3.8 POST-CONSTRUCTION PROGRAM ACTIVITIES The 2010 MS4 Permit requires the City to report the following in the Annual Report as it pertains to the post-construction requirements associated with construction operations:

1. Summary of any new or revised post-construction controls for City projects or post-construction requirements related to permits the City issues.

2. An overview of the city’s post-construction inspection program. 3. Corrective and enforcement actions needed and taken in response to post-

construction inspections. 3.8.1 New or Revised Post-Construction Controls During this reporting period, no changes were made to the Engineering & Design Standards (2012) which incorporates the City’s stormwater drainage and retention standards. A copy of that document is available at the following link: http://www.mesaaz.gov/engineering/MesaStandardandSpecs.aspx 3.8.2 Overview of Post-Construction Inspection Program For private construction projects, the City requires developers to obtain a third party inspection of post-construction stormwater controls to determine effectiveness of these controls. For City projects, the City conducts a final stability inspection for projects involving land disturbance of one or more acres ensure the site has achieved permanent stabilization.

http://www.mesaaz.gov/engineering/MesaStandardandSpecs.aspx


An inspection of this nature is necessary in order to file a Notice of Termination (NOT) to end coverage under the CGP. 3.8.3 Summary of Corrective and Enforcement Actions For private construction projects, a certificate of occupancy will not be issued until such a time that the developer provides a third party inspection of post-construction stormwater controls for projects requiring such an inspection. The City files a NOT to end coverage under the CGP for each project that disturbed one or more acres of land based on the results of the final stability inspection. Where final stabilization has not been achieved, coverage under the CGP is maintained. This may occur in instances where one general contractor’s scope of work did not include final stabilization (e.g. application of ground cover) but that this would be achieved under another project phase, either by City personnel or another general contractor. 3.9 DRY-WEATHER SCREENING The 2010 MS4 Permit requires the City to report the status of the following in the Annual Report as it pertains to the dry-weather screening requirements:

1. Staff training. 2. Outfall and field screening point inventory. 3. Inspection tracking system. 4. Inspection and screening procedures and significant findings.

3.9.1 Staff Training The 2010 MS4 Permit requires the existing employees directly involved with stormwater management activities, including dry-weather screening and associated investigations, be trained at least once every two (2) years and to provide an opportunity for new employee training at least one (1) time per year. As such, all City staff who conducts these types of operations must meet the following requirements:

• Review the procedures detailed in the Environmental Code Violation Standard Operating Procedures;


• Have knowledge of: Ordinances, rules, and regulations governing stormwater discharges,

particulate pollution, and hazardous materials; Principles and practices for field monitoring protocols, sample collection,

preservation, analysis, and documentation requirements; Occupational and safety precautions at industrial and construction work sites

(position requirement; and, • Have a basic knowledge of chemicals on human and ecological systems

(position requirement). Dry weather screening inspections involve two personnel for health and safety reasons among others. Dry-weather screening inspections conducted during this reporting period involved personnel that were hired during the reporting year. Training was provided to these personnel prior to conducting dry-weather screening activities. 3.9.2 Outfall and Field Screening Point Inventory No changes to the outfall or field screening point (FSP) inventory were made as a result of the dry-weather screening activities conducted this reporting period. 3.9.3 Inspection Tracking System Dry-weather screening and associated investigations are documented on the Dry-Weather Screening Report Form specific for each location. The City has developed a database with the functionality to retrieve data and generating reports required for the annual report and to better track results at these locations. 3.9.4 Inspection and Screening Procedures and Significant Findings No dry-weather flows were observed at the outfalls or field screening points monitored during this reporting period. 3.10 ORDINANCES, RULES, & POLICIES During this reporting period, the City Council approved revisions to City’s Stormwater Code through ordinance to include the adoption of the Flood Control District of Maricopa County (FCDMC) Drainage Design Manual for Maricopa County – Erosion Control manual detailing best management practices and associated City amendments, which will apply to any stormwater best management practice (BMP) installed on all projects


conducted by the City and under contract to the Engineering Department or another City department and/or any City property; including, public right-of-way areas (e.g. city owned and operated streets, catch basins, scuppers, etc.). A copy of the City’s revised Stormwater Code is provided as an attachment to this Annual Report (see Section 13.5 and Attachment B. 3.11 FISCAL EXPENDITURES See Section 12.0.


4.0 STORMWATER PROGRAM NUMERIC SUMMARY The 2010 MS4 Permit requires the City to provide a summary of management practices and activities performed each year and to report that summary in a table as provided in that permit. Attached in this section is the table summarizing activities conducted under the City’s 2010 MS4 Permit.

Notes for current reporting period:

NA- Not Applicable

(2) One facility assessment has a potential to require this type of plan. The City is working on alternative storage options at this facility.

(9) Quantity reported in tons.

(11) Between summer 2008 and summer 2012 the City conducted a concentrated effort to target the cleaning of every City owned catch basin. The recent drop in numbers is attributed to the City returning to a regular preventative maintenance schedule.

(1) During this reporting period, the City developed a training database to track employee training for all environmental training program areas. These numbers have been adjusted because previously reported number double counted some personnel.

(8) The City is continuing to develop an accurate method to track the number of miles of MS4 prioritized for inspection and inspected.

Post Construction Program Activities

Construction Program Activities

(5) The remaining three cases were still open at the end of this reporting period.

(10) The City has 174 basins in its inventory. Some basins are cleaned more frequently than others. Reported value is the total number of times City owned and operated basins were cleaned.

(3) To date, the City has not identified any conditions at outfall or field screening point locations that meet the definition of a "priority outfall" as provided in the 2010 MS4 Permit.

(6) Storm drain inspections were not required during this reporting period, since no dry-weather flows were identified at outfall or field screening point locations.

(4) Reported illicit discharges were the result of those called in as a complaint. No dry-weather flows at outfall or field screening points were identified during this reporting period from dry-weather screening operations.

(7) Municipal facility assements were completed during the reporting period, however, the City did not complete the stormwater evaluation of these sites as of the end of this reporting period (June 30, 2013). Actual date evaluaton was completed is provided.


5.0 EVALUATION OF THE STORMWATER PROGRAM The 2010 MS4 Permit requires the City to provide an evaluation of the progress and success of the City’s stormwater management program, including an assessment of the effectiveness of stormwater management practices in reducing the discharge of pollutants to and from the City’s MS4 in the Annual Report. 5.1 PROGRAM PROGRESS The City has drafted the following standard operating procedures addressing the requirements provided in the 2010 MS4 Permit. The most current date of these procedures is also provided.

• Commercial & Industrial Facility Inspection Standard Operating Procedures (September 2011)

• Environmental Code Violation Standard Operating Procedures (September 2011) • Environmental Program Training Standard Operating Procedures (February

2012) • Standard Operating Procedures for City Facility Compliance Assessments

(February 2012) • Standard Operating Procedures for City Field Operations Activities (September

2011) • Standard Operating Procedures for City Stormwater Infrastructure Operations

Activities (March 2011) • Standard Operating Procedures for Construction Activities of City Projects

(March 2011) • Standard Operating Procedures for Construction Activities of Private Projects

(September 2011) • Standard Operating Procedures for Stormwater Monitoring (currently in draft) • Wet-Weather Stormwater Sampling & Analysis Plan (April 2011) • Standard Operating Procedures for Stormwater Monitoring (October 2012)

Many of these procedures incorporate other City requirements established under the Mesa City Code that are not specific to the City’s stormwater program.


5.2 PROGRAM SUCCESSES During this fiscal year, the following successes to the City’s stormwater program include:

• The City passed and incorporated the revisions to the Title 8, Chapter 5, Storm Water Pollution Control of the Mesa City Code.

• The STORM organization conducted radio PSA that reached an estimated 3.2 million people over the Greater Phoenix Metropolitan Area.

• STORM sponsored the LID workshop that attracted approximately 122 attendees.

• The 2013 Industrial Stormwater Compliance Made Easy seminar provided by STORM attracted approximately 84 attendees.

5.3 REDUCTION OF POLLUTANTS TO THE CITY’S MS4 Elements of the City’s stormwater program that the City identifies as having significantly reduced the release of pollutants to their MS4 include:

1. Public Education & Outreach 2. Public Reporting (i.e. Environmental Hotline) 3. Household Hazardous Waste Events 4. Commercial & Industrial Facility Inspections 5. Construction Site Inspections

5.3.1 Public Education & Outreach The STORM organization’s radio PSA campaign was a major benefit to the City’s stormwater program by providing information pertaining to proper disposal of swimming pool water. The LID workshop was a major benefit to the City’s stormwater program by providing information regarding stormwater design alternatives to City staff in attendance at the workshop. This information will be valuable for the City is assessing low-impact alternatives as required by the 2010 MS4 Permit for the following reporting period. STORM’s 2013 Industrial Stormwater Compliance Made Easy seminar provided information on the selection and proper installation and maintenance of BMPs for industrial facilities that were required to obtain coverage under the ADEQ MSGP. A


copy of the information from that seminar was also placed on the STORM website for attendees and those operators who could not attend. This seminar helps to reduce the amount of pollutants discharged to the City’s MS4 by providing industrial site operators with increased knowledge of what is required on their facilities. 5.3.2 Public Reporting By providing a public reporting method for complaints regarding stormwater issues, the City is able to identify and take timely action against persons who are responsible for releasing pollutants to the City’s MS4. Additionally, this information can be used to determine what topics need to be further addressed though the STORM organization’s public education and outreach program. 5.3.3 Household Hazardous Waste Events The City’s HHW events collected over 65,000 gallons of waste. It is not possible to quantify the amount of HHW that could be released into the storm sewer system if the HHW events were not held. However, since material collected at the events is disposed of properly, these events ultimately result in significantly reducing releases of these types of pollutants to the City’s MS4. 5.3.4 Commercial & Industrial Facility Inspections City inspectors conduct inspections on a daily basis of commercial facilities that require permitting under the City’s FOG program. These inspectors are trained to identify violations of the City’s Stormwater Code and to report such violations to appropriate City personnel. The inspections of industrial facilities by qualified personnel to identify violations of the City’s Stormwater Code are also an effective method for reducing the release of pollutants to the City’s MS4. Through the issuance of a courtesy notice requiring corrective actions, the City is able to have the source of pollutants removed by the responsible party while at the same time providing a public education opportunity to prevent future discharges and encourage public reporting. Where necessary, the City does have the authority to pursue civil and criminal actions against responsible parties if they refuse to take action, take action then recommit the offense, or commit offences in a manner that they are considered habitual offenders. These enforcement actions, or the threat of them, can be an effective tool in accelerating corrective actions by the responsible party.


5.3.5 Construction Site Inspections City inspectors conduct inspections of private construction projects to ensure they are operating in compliance with the City’s Stormwater Code. Where issues are identified, City inspectors have the authority to issue a “Stop Work Order” or otherwise not approve contractor improvements (similar to a Stop Work Order) as a mean of obtaining compliance until such time that the issues have been adequately addressed. Where necessary, the City does have the authority to pursue civil and criminal actions by establishing a code compliance case against responsible parties if the construction site operator refuses to take action, takes action but then recommits the offense, or commits offences in a manner that they are considered repeat offenders. These enforcement actions, or the threat of them, can be an effective tool in accelerating corrective actions by the responsible party. 5.4 REDUCTION OF POLLUTANTS FROM THE CITY’S MS4 Elements of the City’s stormwater program that the City identifies as having significantly reduced the discharge of pollutants from their MS4 to waters of the United States include:

1. MS4 Infrastructure Maintenance 2. Post-Construction Requirements

5.4.1 MS4 Infrastructure Maintenance Maintenance of the City’s MS4 System results in the direct removal of pollutants from the system, thus keeping them from being discharged into a water of the United States. 5.4.1.1 Street Sweeping Sediment and debris that collects on paved streets owned and operated by the City is removed through the City’s street sweeping program. The estimated amount of pollutants removed from the City’s street sweeping program is provided in the Numeric Summary of Stormwater Management Program Activities table in Section 4.0. 5.4.1.2 Storm Sewers Components The City has a program to clean catch basins, storm pipes, open channels, headwalls and culverts that are owned and operated by the City. Removal of trash, debris and


sediment from these structures prevents this material from being discharged to a water of the United States. 5.4.1.3 Detention/Retention Basins The City owns and operates several detention and retention basins installed throughout the City. Much of the City’s streets and storm pipes drain to a detention or retention basin at some point before potentially draining to another regulated MS4 or a water of the United States. The City removes debris, trash, and sediment from detention basins to keep pollutants from discharging further into the City’s MS4. The removal of these pollutants from retention basins keeps these basins operational and allows for the infiltration of stormwater. 5.4.2 Post-Construction Requirements The City has developed an Engineering and Design Standards Manual that provides specific direction and guidelines to the design professionals preparing construction documents for private land development projects. That manual adopts the Uniform Drainage Policies and Standards for Maricopa County as published by the Flood Control District of Maricopa County with modifications as specified within that manual. City regulations requiring the retention of the 50-year, 24-hour run-off volume were adopted in 1997 and were based on three (3) inches of precipitation. Subsequent development in the City has been required to retain rainfall from a 100 year, 2-hour storm event either through the City’s retention standard since these requirements were adopted in the late 1980’s. The retention standard results in the reduction of pollutants discharged from the City’s MS4 to a water of the United States.




6.0 STORMWATER MANAGEMENT PROGRAM MODIFICATIONS The 2010 MS4 Permit requires the City to provide a description of the modifications to the City’s SWMP for the areas described in the following subsections. No other changes to the City’s SWMP are allowed without permit modification. 6.1 ADDITION OF NEW CONTROL MEASURES No additional control measures apart from those required in under the 2010 MS4 Permit were implemented during this reporting period. 6.2 ADDITION OF TEMPORARY CONTROL MEASURES No temporary control measures were implemented during this reporting period. 6.3 INCREASE OF EXISTING CONTROL MEASURES No increases to existing control measures were implemented during this reporting period. 6.4 REPLACEMENT OF EXISTING CONTROL MEASURES No existing controls were deemed to be ineffective and replaced with an alternate control measure that will continue to achieve an equivalent or increased reduction in pollutants during this reporting period.




7.0 MONITORING LOCATIONS The 2010 MS4 Permit requires the City to provide a brief description of the City’s wet-weather stormwater monitoring locations in the first annual report. Subsequent annual reports need only advise of any changes or updates that were required. The information required includes the following:

1. Name and description of water of the United States receiving discharges from the monitoring location;

2. Monitoring location identification number (see subsection titles); 3. Address or physical location of the monitoring locations; 4. Latitude and longitude of monitoring locations; 5. Size (acres) of drainage area associated with each monitoring location; 6. Estimated acreage of individual land uses with each drainage area; and, 7. Type of monitoring equipment

The City provided information regarding items 1, 2, 3, 4, and 7 in the Annual Report dated September 2011. Engineering & Environmental Consultants, Inc. (EEC) was contracted by the City under the request for proposal process for stormwater program development to conduct a study that would update the City’s pollutant loading model. The study included delineating drainage areas for each outfall and FPS location, estimating the total acreage of each drainage area, and estimating the acreage of each land use within each drainage area that results in a discharge to a water of the United States (see Section 11.0). EEC evaluated each outfall and FSP for the following land uses: streets, residential, commercial, industrial, lawns/parks, hillside/mountain, desert, and agricultural. Please note that the streets land use did not include streets incorporated in commercial and residential areas. This information was incorporated into the City’s Standard Operating Procedures for Stormwater Montioring manual. The following sections provide information for each sampling sampling location.


7.1 AS-US60 The total drainage area for this location is approximately 149.3 acres and is broken down as follows:

• Residential – 128.5 • Agricultural – 0.0 • Commercial – 20.8 • Industrial – 0.0 • Lawns/Parks – 0.0 • Desert – 0.0 • Hillside/Mountain – 0.0 • City Streets – 0.0

7.2 SS-US60 The total drainage area for this location is approximately 6.5 acres and is broken down as follows:


7.3 54-EMF The total drainage area for this location is approximately 29.3 acres and is broken down as follows:

• Residential – 29.3 • Agricultural – 0.0 • Commercial – 0.0 • Industrial – 0.0


• Lawns/Parks – 0.0 • Desert – 0.0 • Hillside/Mountain – 0.0 • City Streets – 0.0

7.4 UN-EMF The total drainage area for this location is approximately 352.4 acres and is broken down as follows:


7.5 FF-ACES The total drainage area for this location is approximately 73.78 acres. Land use data was not evaluated for this location since this sampling location did not meet the definition of an “outfall” or “FSP” as provided in the scope of work for the EEC study. However, this sampling location is interior to the Falcon Field Airport which is a regulated industry under the ADEQ’s Multi-Sector General Permit. As such, all this area is known to be industrial use.




8.0 STORM EVENT RECORDS The 2010 MS4 Permit requires the City to summarize all measurable storm events (0.10 inches or greater) at each monitoring location until such a time that stormwater samples have been collected at that particular monitoring location during that particular season. The information is to include the following:

• Date of each event; • Amount of precipitation of each event; • Indication of whether or not a sample was collected as part of the event; • Information on conditions that prevented the collection of a sample.

Attached in this section is a table summarizing storm event records obtained under the 2010 MS4 Permit.

Notes:

(1) Seasons: Summer (S): June 1st through October 30th (highlighted yellow). Winter (W): November 1st through May 31st (highlighted blue).(2) Flood Event: Storm intensity exceeding the 100 Year, 2-Hour storm event (i.e. >2.2 inches in two hours).(3) Normal Storm: Storm intensity up to and including the 100-year 2-hour duration storm event (i.e. < 2.2 inches in two hours). (4) Insufficient Rainfall: Rainfall intensity below design storm requirments (i.e. less than 0.10 inches per hour).(5) Where sufficient rainfall did occur, indicate one of the following results and/or describe in the "Notes" section:

DS (Dangerous Storm): Adverse climatic conditions existed that created a dangerous condition for stormwater monitoring staff (e.g. local flooding, high winds, lightening, etc.). Generally for discrete sampling only. DWF (Dry-Weather Flow): Dry-weather flows were identified prior to event that may contain quantities and concentrations of pollutants that would significantly alter stormwater samples. EM (Equipment Malfunction): Equipment failed to enable to collect a composite sample or failed to notify stormwater monitoring personnel that a representative storm had occurred. HE (Human Error): Sampling was not conducted due to human error. HT (Hold Time): Permit requires sampling events for each location to be at least 72 hours since the last storm event discharge (i.e. flow in response to rainfall). IF (Insufficient Flow): Storm did not result in a level reading of two or more inches at the monitoring location. IM (Insufficient Manpower); Storm occurred during off-hours where a less than 20% chance of rain was forecasted and/or appropriate stormwater monitoring personnel were unavailable to respond. IS (Insufficient Sample): Did not collect enough aliquots to qualify as a flow proportional composite sample. NR (Not Required): Samples have been collected for all analyses for current season. SC (Sample Collected): Sample was collected during this storm event.


9.0 SUMMARY OF MONITORING DATA The 2010 MS4 Permit requires the City to provide a summary of monitoring data (by location) using a table format as provided in Appendix B of that permit. Instructions stated that the City was to use a separate table for each monitoring location, to enter the analytical results for the stormwater samples collected for each season of the reporting period for each year, to enter subsequent monitoring data for each location on the same form, and to include, as an attachment, the laboratory reports for stormwater samples. The information in the table provided was to include the following:

• The monitoring location identification number; • The receiving water; • Designated uses; and, • The lowest surface water quality standards applicable to the receiving water.

Attached in this section are tables summarizing stormwater monitoring data obtained under the 2010 MS4 Permit. The laboratory analytical reports are included as an attachment to this Annual Report (see Section 13.4 and Attachment A). During this reporting period, the City worked with its contract laboratory to improve analytical methods in order to address method detection limit that are above the respective surface water quality standard (SWQS). The detection limits for several parameters were successfully lowered for several parameters which can be identified between the winter 2011-12 and summer 2012 analytical results in the attached tables. The 2010 MS4 Permit requires the City to collect samples for a full set of analyses (includes volatile organic compounds, semi-volatile organic compounds, and pesticides) once each wet season every other year and the remaining parameters once each wet season every year beginning in Winter 2010. Due to the time needed to relocate the four of the sampling locations and re-equipping the remaining location and the lack of rainfall once they did become active, the first set of samples were not collected until the summer 2011 sampling period. Also, due programming and trouble-shooting issues during the 2011 sampling period, the City was unable to collect the “full set” from most


locations. Therefore, the first “full set” of analyses for all stations was collected during the winter 2011-2012 sampling season. The City will therefore be collecting samples for the full set of analyses during the following seasons:

• Winter 2011-12 • Summer 2012 • Winter 2013-14 • Summer 2014

Notes:Bold values were reported at levels above the laboratory method reporting limit (MRL). Non-bold values are the MRL. Shaded results were detected above the SWQS.See attached laboratory analytical reports for flagged data.1) Analytical results shall be reported in the units specified for each category or parameter.

Shaded Cells (results columns): Red - Detected above SWQS; Orange - Not detected, but reported above EDW SWQS; Green - Not detected, but reported above PBC SWQS.3) Average flow rate for the sampling period (no more than 6 hours). 4) pH range (maximum/minimum).5) Comparison of temperature at point of discharge is upgradient from the nearest stream segment having established SWQSs and is thus not relevant at proposed sampling locations.6) Based on free-cyanide.

8) Based on total chromium.9) Depends on pH. Reported values are for pH of 7.0. Where field parameters (i.e. discrete samples) are not collected during the same storm event, the SWQS associated with a pH 7.0 will be used.10) Methods: These parameters may be run using the following methods: VOCs, 624 or 8260; SVOCs, 625 or 8270; and PCB / Pesticides, 608/625 or 8081/8082 if the laboratory can pass QA with the method. 11) SWQSs reported for total xylenes.12) Also known as p-nitrophenol.13) SWQSs report as total endosulfan.14) SWQSs reported as PCBs

7) SWQS for total metals is provided and based on partial body contact. The SWQS for disolved metal concentration for effluent dependent water is dependant on the hardness value for each sample and will in most cases be below the SWQS for partial body contact.

2) Surface Water Quality Standards (SWQSs) established for Salt River segment extending from City of Mesa NW WRF outfall at 33°26'45"/111°56'35" to Tempe Town Lake at 33°26'01"/111°54'55". Partial Body Contact (PBC, shaded in brown) and Aquatic and Wildlife Effluent Dependent Water (A&Wedw, shaded in pink).

10.0 ASSESSMENT OF MONITORING DATA The 2010 MS4 Permit requires the City to:

1. Provide an evaluation of the sampling results for each monitoring location, including an assessment of any improvements or degradation of stormwater quality from each drainage area;

2. Compare the sampling results for each monitoring location with the applicable SWQSs;

3. Note any exceedance of SWQSs for the water of the United States receiving discharges during the reporting year; and,

Additionally, the 2010 MS4 Permit provides that where monitoring data results show a recurring (more than once) exceedance of a SWQS at a monitoring location, the City shall investigate and make all reasonable efforts to identify potential source(s) of the pollutant(s) and to report this information in the annual report (see Section 4.2 and Section 8.3 of the 2010 MS4 Permit). Furthermore, in the fourth year annual report (due September 30, 2014), the City was to include a discussion of possible explanations for stormwater quality trends, including the implementation of stormwater management practices to reduce the discharge of pollutants to and from the storm sewer system. 10.1 SURFACE WATER QUALITY STANDARDS SWQSs associated with the water of the United States that has a potential to receive discharges from each monitoring location is provided with the summary of monitoring data tables in Section 9.0. 10.2 EXCEEDANCES OF SURFACE WATER QUALITY STANDARDS Exceedances of SWQSs for are identified in the summary of monitoring data tables in Section 9.0. Exceedances of established SWQSs are shaded in red. In some cases, the results were non-detection but the established method detection limits were reported above the SWQS. These are shaded in either orange for Aquatic & Wildlife SWQSs or green for Partial Body Contact SWQSs.


10.3 STORMWATER QUALITY EVALUATION - BY LOCATION The evaluation of stormwater quality for each monitoring location is provided below. An overall evaluation of stormwater quality based on the pollutants detected above applicable SWQSs is provided in Section 10.4. 10.3.1 Station AS-US60 Analytical results indicate that concentrations of E. coli, copper, lead, and zinc were detected above the applicable SWQSs. E. coli results average 1,643 under the Most Probable Number (MPN) method with a standard deviation of 500. Copper results average of 65 parts per billion (ppb) with a standard deviation of 23. Lead results average 13 ppb with a standard deviation of 3. Zinc concentrations average 11 ppb with a standard deviation of 96. Concentrations of lead are consistent with the other sites, and the reason these exceed the SWQSs at this location is solely due to the fact that this site discharges to an effluent dependent water where the other sites discharge to an ephemeral water. Concentrations of copper at this location trend to be higher than the other locations and may be attributed to a denser population and a lower degree of on-site retention in the associated drainage area. The results do not appear to show a pattern for determining an improvement or degradation of stormwater quality. 10.3.2 Station SS-US60 Analytical results indicate that concentrations of E. coli and copper were detected above the applicable SWQSs. E. coli results average 3,560 MPN with a standard deviation of 3,169, indicating sporadic results. Copper results average of 32 ppb with a standard deviation of 7 indicating a strong consistency between sampling events. The results do not appear to show a pattern for determining an improvement or degradation of stormwater quality. 10.3.3 Station 54-EMF Analytical results indicate that concentrations of E. coli and copper were detected above the applicable SWQSs. E. coli results average 1,346 MPN with a standard deviation of 702. Copper results average of 30 ppb with a standard deviation of 7 indicating a strong consistency between sampling events. The results do not show a pattern for determining an improvement or degradation of stormwater quality.


10.3.4 Station UN-EMF Analytical results indicate that concentrations of E. coli and copper were detected above the applicable SWQSs. E. coli results average 4,358 MPN with a standard deviation of 4,592, indicating sporadic results. Copper results average of 31 ppb with a standard deviation of 1 indicating a strong consistency between sampling events. The results do not show a pattern for determining an improvement or degradation of stormwater quality. 10.3.5 Station FF-ACES Analytical results indicate that concentrations of copper detected above the applicable SWQSs. Copper results average of 17 ppb with a standard deviation of 6 indicating a strong consistency between sampling events. The results do not show a pattern for determining an improvement or degradation of stormwater quality. 10.4 SWQS EXCEEDANCE INVESTIGATIONS When a reoccurring exceedance of a SWQS is identified, the City will conduct dry-weather screening to visually inspect the outfall/FSP for flow (similar to that for an IDDE investigation). If flow is present, then the City would conduct a dry-weather investigation as described in the City’s Environmental Program Training Standard Operating Procedures which may include:

• Conducting a drainage area investigation; • Conducting a storm drain network investigation; • Conducting a subsurface investigation (e.g. video survey); or • Conducting additional monitoring.

If dry-weather flow is absent, or if the source of the flow is identified but determined not be a contributing source of the pollutant(s) exceeding the SWQS, the City will conduct a modified drainage area investigation which goes beyond looking for dry-weather flows. In order to address the metals and E. coli concentrations detected at sampling stations AS-US60, SS-US60, 54-EMF, and UN-EMF, the City conducted dry-weather screening


at each of the outfall/FSP locations. This investigation took place in May 2012. No dry-weather flow was identified. The City also conducted a modified drainage area investigation of each of these drainage areas. In conducting these investigations, City personnel drove through the drainage area in order to identify potential sources of the pollutants of interest, including roadway frontages, alleyways, and streets. This also included creating an inventory of all commercial and industrial operations that exist in these areas and conducting a cursory inspection of these operations to determine if a point source could be linked to these operations. Based on the City’s drainage area investigation no point sources for metals or E. coli could be identified. The 2010 MS4 Permit requires the City to, where a source is identified that can be linked to a reoccurring exceedance of a SWQS, immediately either work to eliminate the source; or, modify existing control measures or implement additional control measures within the control of the City that may reduce a recurring discharge of the identified pollutant(s) to the maximum extent practicable in the area the exceedance has been identified. Since the City was unable to determine a source of these contaminates, no subsequent actions were taken by the City. Please note, for sampling station FF-ACES, this is installed in an interior location at the Falcon Field Airport. This facility is permitted under the ADEQ MSGP. As such, the “outfalls” at this facility are monitored for dry-weather flows annually, and an inspection of the facility is conducted annually to meet the requirements of the MSGP. As such, the City will not be conducting any additional investigations regarding SWQS exceedances for the purposes of this permit if/when and exceedance is identified.


11.0 ESTIMATE OF POLLUTANT LOADING The 2010 MS4 Permit requires the City to provide an estimate of the pollutant loadings each year from the City’s MS4 to waters of the United States for the following constituents:

• Biological Oxygen Demand; • Chemical Oxygen Demand; • Total Suspended Solids; • Total Dissolved Solids; • Total Nitrogen; • Total Ammonia; • Total Organic Nitrogen; • Total Phosphorous; and, • Metals.

The 2010 MS4 Permit also requires the City to include a description of the procedures for estimating pollutant loads and concentrations, including any modeling, data analysis, and calculation methods and to compare the pollutant loadings estimated each year to previous estimates of pollutant loadings. 11.1 POLLUTANT LOADING MODELING, DATA ANALYSIS, AND CALCULATIONS To meet the conditions of the 1997 Phase I Permit conditions, the City developed a model to estimate total pollutants discharged from the City’s MS4 using the “simple method” as described in EPA’s “Guidance Manual for the Preparation of Part 2 of the NPDES Permit Applications for Discharges from Municipal Separate Storm Sewer Systems.” As provided in the USEPA guidance, the regulation required system wide (cumulative) annual pollutant load calculation for each of the required pollutants, but that the single pollutant load values provide limited insights into potential problem areas and what BMPs might yield the best results. Consequently, the City decided to use the simple method to estimate “individual” pollutant loadings from drainage areas as referenced in the USEPA guidance. The individual pollutant loadings were then aggregated to derive a cumulative annual


pollutant loading for the entire MS4. The pollutant loading model developed by the City was managed in an Excel® format. The City contracted Engineering and Environmental Consultants, Inc. (EEC) to update the model by:

• Conducting an assessment of rainfall data; • Conducting an assessment of the drainage areas associated with each of the

outfall and FSP locations; • Evaluating weighted average of runoff coefficient data associated with land

uses; • Re-developing the City’s model to incorporate the results of the above studies;

and, • Providing a report summarizing the steps taken in preforming these analyses.

In addition, EEC worked with the City in re-designing the Event Mean Concentration (EMC) table that was used in the 1997 Phase I Permit. 11.1.1 Event Mean Concentration Sampling data duirng the 2010 MS4 Permit (September 2010 through August 2015) will be used to calculate the EMC as provided in the equation below.

EMC = Sum of Sampling Data Number of Data Points

The EMC table was modified to include parameters required in the 2010 MS4 Permit and to remove parameters that were previously modeled as part of the 1997 Phase I permit but were not required to be modeled in the 2010 MS4 Permit. 11.1.2 Rainfall Data Evaluation Rainfall data obtained from the FCDMC rain gages located within the City’s incorporated area were analyzed in two ways.

1. Using data from the last five years, excluding any rain events that exceeded the 100-year 2-hour storm event - estimated at 6.99 inches.


2. Using all available FCDMC data for the 12 rain gauges and did not exclude rain events exceeding the 100-year 2-hour storm event – estimated at 7.12 inches

Due to highly variable rainfall events from year to year and the impact of particularly dry or wet years is greater in smaller datasets, EEC recommended using 7.12 inches of rainfall for the average annual rainfall in the pollutant loading model. 11.1.3 Drainage Area Runoff Volumes Drainage areas runoff volumes were determined or each outfall and FSP using the following formula.

V = P * CF * WC * A 12 Where: V = Annual volume discharged from drainage area (acre-feet). P = Annual precipitation (7.12 inches/year, see Section 7.2.2). CF = Correction factor that adjusts for storms where no runoff occurs (0.9 used

per USEPA guidance). WC = Weighted average runoff coefficient. A = Drainage area. 11.1.3.1 Drainage Area Evaluation EEC evaluated the drainage areas of approximately 170 outfall and FSP locations identified by the City. The drainage area evaluation included deliniating the drainage areas included topography, storm drain line, and flow direction arrow data that was provided to EEC in the form of GIS layers of the City’s storm sewer system. This evaluation also included the use of aerial photos along with best professional judgment used to make assumptions on the probable grading and drainage patterns. The total acreage of each drainage area was then estimated and new GIS layers illustrating each drainage area were created. The drainage area evaluation also included determining various land uses whithin each drainage area. The land use areas were determined using City GIS land use data and information from the City’s the Storm Drain Master Plan. The land uses were simplified


into eight categories corresponding to land uses including streets, residential, commercial, industrial, lawns/parks, hillside/mountain, desert, and agricultural. Streets within residential and large commercial and industiral areas were not separated out from the surronding land uses. The streets land use was generally limited to drainage areas that primarily drained only City streets. 11.1.3.2 Weighted Average Runoff Coefficient EEC reveiwed published runoff coefficients and recommended using those provided in the FCDMC hydrology manual for the purposes of the City’s pollutant loading model. EEC also recommended using the runoff coefficients as listed in the FCDMC Manual corresponding with the selected land uses for the 2-year storm event. The only exception to this was the ‘Residential’ coefficients, since the FCDMC runoff coefficients published for residential land use did not include adjacent streets. For these, the average between the 2 and 10 year events was used. Based on EEC’s evaluation and recommendations, the City’s pollutant loading model has incorporated the weighted average runoff coefficients as provided below.

Land Use Wighted Average Runoff Coefficients Residential (very low or low density) 0.41 Residential (medium or high density) 0.63 Commercial 0.65 Industrial 0.65 Lawn/Parks 0.18 Desert 0.37 Hillside / Moutain 0.48 City Streets 0.75

11.1.4 Annual Pollutant Loading Estimate The City uses the following to calculate the annual loading.

L = V * C * 0.00136

L = Annual pollutant load (tons/year). V = Annual volume discharged (acre-feet). C = Pollutant Event Mean Concentration determined from the sampling

program (mg/L).


0.00136 = Conversion factor The pollutant loading is calculated for each required constituent, and volume discharged was the sum of individual drainage areas that discharged stormwater to the Salt River or the EMF. A copy of the pollutant loading estimates for each parameter required to be modeled is attached to back of this section. 11.2 COMPARISON OF POLLUTANT LOADING ESTIMATES A comparison between the 2011-2012 reporting year and this year’s pollutant loading estimates indicate consistency in the total pollutant loads and does not show a pattern for determining an improvement or degradation of stormwater quality.

12.0 ANNUAL EXPENDITURES The 2010 MS4 Permit requires the City to provide a brief statement of the expenditures incurred each reporting period (July 1 – June 30) related exclusively to implementing and maintaining the stormwater management program, including associated monitoring and reporting activities. Additionally, the 2010 MS4 Permit requires the City to provide the estimated budget for implementing and maintaining the stormwater program in the subsequent reporting period and to include a statement of the funding sources used to support program expenditures. The City’s stormwater program during this reporting period was funded in part from an Environmental Fee that is assessed to City residents and businesses as part of their utility bills and the remaining was funded from the City’s General Fund. An Annual Expenditure Report is included as an attachment to this Annual Report (see Section 13.9 and Attachment E).




13.0 ATTACHMENTS The 2010 MS4 Permit requires the City to attach the following to the Annual Reports:

1. Drainage system maps 2. List of major outfalls and field screening points 3. List of changes to the major outfalls and field screening points inventory (new,

out of service, other changes), including drainage area and coordinates for the monitoring locations listed in Table 1 of the permit (4th year report)

4. Laboratory reports for stormwater monitoring performed in the reporting period 5. New or revised ordinances associated with stormwater management 6. New or revised public outreach documents

Other attachments include:

1. Household hazardous waste reports; 2. Updated City facility inventory; and, 3. Annual expenditure reports.

13.1 DRAINAGE SYSTEM MAPS The City considers the exact location of its utility infrastructure to be confidential and for use by City personnel only. As such, the City cannot supply this information as an attachment to this document. The City would be able to supply this information to the ADEQ upon official request and only under a signed confidentiality agreement or provide a presentation of this information to the ADEQ upon request. 13.2 LISTING OF OUTFALLS & FIELD SCREENING POINTS No changes to the listing of outfalls and FSPs were made during this reporting period. See the Stormwater Annual Report for reporting period July 2012 – June 2013 for the most recent version of this information, so this information has not been supplied in this year’s report. 13.3 LIST OF CHANGES TO OUTFALL & FIELD SCREENING POINTS No changes to the listing of outfalls and FSPs were made during this reporting period. See the Stormwater Annual Report for reporting period July 2012 – June 2013 for the

2. For construction operations at City projects or occurring in the City of Mesa public right-of-way that are required to comply with and AZPDES or NPDES Storm Water Permit, that certain document known as the Drainage Design Manual for Maricopa County, Erosion Control dated November 28, 2012, a public record of the City of Mesa together with the following appendices thereto: (2774, 5062, 5144/Reso. 6528)

Appendix A Construction General Permit (5144)

Appendix B Forms (5144)

Appendix C Links and References (5144)

Appendix D Glossary (5144)

Appendix E Bibliography (5144)

Are hereby referred to, adopted, and made a part hereof as if fully set forth in this Section, with the following changes in and amendments to said document: (5144)

(a) Section 5 Best Management Practices; EC-2: Mulching Emulsified asphalt is not permitted as a mulching option on City properties or for City projects. (5144)

8-5-3 8-5-3

(b) Section 5 Best Management Practices; EC-3 Protection of Trees and Vegetation in Construction Areas Where plans provide for the preservation of trees and other vegetation, these areas shall be delineated (i.e. staked, flagged, or fenced) to prevent damage from construction equipment and other forms of access. (5144)

(c) Section 5 Best Management Practices; EC-5 Stabilized Construction Entrance Course aggregate pad dimensions must be a minimum of thirty feet in width, three inches in depth, and fifty feet in length or the length of the longest haul truck, whichever is greater. Instead of a course aggregate pad, construction site entrance stabilization may also include a paved surface one hundred feet in length and twenty feet in width or a grizzly or rumble grate consisting of raised dividers a minimum of three inches tall, six inches apart, and twenty feet in length. (5144)

(d) Section 5 Best Management Practices; SPC-2 Sand Bag Barrier Sand bags may not be used for the purposes of inlet protection. Where sand bags are used for other purposes, they shall be delineated (i.e. staked and flagged) to keep construction equipment from damaging these structures. Sand bags must be inspected on at least a weekly basis to ensure they have not ruptured and the sand has become a stormwater pollutant. (5144)

(e) Section 5 Best Management Practices; SPC-5 Silt Fence For projects greater than five acres requirements regarding perimeter control of the construction activity as provided in any applicable stormwater permit shall be met through the use of silt fences excepting those areas of high flow, construction site entrances, areas where perimeter control are impracticable (i.e. projects in the public right-of way); and areas where all stormwater flows are directed to an on-site temporary sediment basin or sediment trap. (5144)

(f) Section 5 Best Management Practices; SPC-6 Re-Vegetation Where plans provide for re-vegetation, installation of such vegetation shall take place as soon as practicable and these areas shall be delineated (i.e. staked, flagged, or fenced) to prevent damage from construction equipment and other forms of access. (5144)

(g) Section 5 Best Management Practices; SPC-7 Storm Drain Inlet Protection To prevent flooding issues, storm drain inlet protection should only be used when sufficient construction site perimeter control is not possible (e.g. utility installations in public roadways or other public right-of-way areas). City of Mesa personnel may remove any storm drain inlet protection device where flood conditions may exist. It is the responsibility of the operator in charge of day-to-day operations to replace or re-install these devices after the threat of flooding has subsided. (5144)

Course gravel and cinder block configurations and sand bags are not to be used to protect storm drains. When installing any storm drain inlet protection that is installed above grade traffic control devices must be placed at the end of both sides of the installation to prevent damage from public and construction traffic, all traffic control devices must be installed in accordance with temporary traffic control requirements as provided in Title 10, Chapter 10 of the Mesa City Code. (5144)

(E) Persons having the potential to cause a release of pollutants to the City storm sewer system and who are required to submit a notice of intent to comply with an AZPDES or NPDES Storm Water Permit shall provide a copy of any approval or statement of authorization from the permitting agency to the City Manager or designee. Where a waiver is available, a copy of that waiver must then be provided in lieu of the approval or statement of authorization. The City will not issue a construction permit nor will verbal authorization be given to proceed with initial grading and drainage operations until the approval or statement of authorization from the permitting agency has been submitted to the City. (2774, 5062, 5144/Reso. 6528)

(B) Nothing in this Section shall preclude City employees from seeking voluntary compliance with the provisions of this Chapter or from enforcing this Chapter through notices of violation, warnings, or other informal devices designed to achieve compliance in the most efficient and effective manner under the circumstances. (5062)

8-5-6: REMEDIES NOT EXCLUSIVE: (5062)

8-5-7: DEFENDANTS AND RESPONSIBLE PARTIES: (5062)

Any responsible party who causes, permits, facilitates, aids, or abets any violation of this Chapter or who fails to perform any act or duty required pursuant to this Chapter, is subject to the enforcement provisions of this Chapter.

(5062)

8-5-8: CIVIL VIOLATIONS AND CITATION: (5062) (A) A civil action for violations of this Chapter may be commenced by issuance of a citation. (5062)

(B) The citation will be substantially in the form established by the City Manager or designee.

The citation shall direct the responsible party to pay the civil sanction and all applicable fees in accordance with Section 8-5-9 of this Chapter within the time period specified on the citation or to appear before the Civil Hearing Officer within the time period specified on the citation and admit or deny the allegations contained in the citation. The Civil Hearing Officer may permit amendments to the citation if substantial rights of the responsible party are not thereby prejudiced. The citation shall be served pursuant to the Arizona Rules of Civil Procedure. (5062)

8-5-8 8-5-9

(C) The responsible party shall, within the time period specified on the citation or within 10 calendar days of the issuance of the citation, whichever is greater, either pay the civil sanction and the fees, or appear in person, through an attorney or by e-mail with the clerk of the Civil Hearing Officer and admit or deny the allegations contained in the citation. (5062)

1. If the responsible party timely pays the civil sanction and the fees, either in person or by mailing payment to the City, the allegations in the citation shall be deemed admitted and such person shall be deemed responsible for having committed the offense(s) described in the citation. If the responsible party appears in person, through an attorney or by e-mail and admits the allegations, the Civil Hearing Officer shall enter judgment against the responsible party in the amount of the civil sanction, plus any applicable fees designated in Section 8-5-9; or, (5062)

2. If the responsible party appears in person, through an attorney or by e-mail and denies the allegations contained in the citation, the clerk of the Civil Hearing Office shall set the matter for hearing. (5062)

(D) If a person served with a citation fails to pay the civil sanction and the fees or to file on or before the time directed on the citation or at the time set for hearing by the Civil Hearing Officer, the allegations in the complaint shall be deemed admitted, and the Civil Hearing Officer shall enter a finding of responsible and a judgment for the City and impose the appropriate sanctions and fees. (5062)

(E) All proceedings before the Civil Hearing Officer shall be informal and without a jury, except that testimony shall be given under oath or affirmation. The technical rules of evidence do not apply, except for statutory provisions relating to privileged communications. If the allegations in the citation are denied, the City is required to prove violations of this Chapter by a preponderance of the evidence. No prehearing discovery shall be permitted, except under extraordinary circumstances as determined by the Civil Hearing Officer. The Civil Hearing Officer is authorized to make such orders as may be necessary or appropriate to fairly and efficiently determine the truth and decide the case at hand. An appeal from final judgments of the Civil Hearing Officer may be taken pursuant to the Arizona rules of civil procedure for special actions. (5062)

(F) Any person aggrieved by a decision of the Civil Hearing Officer, at any time within 30 calendar days after a final judgment has been rendered, may file a complaint of special action in Superior Court to review the Civil Hearing Officer’s decision. Filing the complaint does not stay proceedings on the decision sought to be reviewed, but the court may, on application, grant a stay and on final hearing, affirm or reverse, in whole or in part, or modify the decision reviewed. (5062)

8-5-9: CIVIL PENALTIES: (5062) (A) Any responsible party who is found responsible for a civil violation of this Chapter, whether by admission,

default, or after a hearing, shall pay a civil sanction of not less than $150 or more than $1,500. A second finding of responsibility within 36 months of the commission of a prior violation of this Chapter shall result in an enhanced civil sanction of not less than $250 or more than $2,500. A third finding of responsibility within 36 months of the commission of a prior violation of this Chapter shall result in an enhanced civil sanction of not less than $500 or more than $2,500.

(5062)

8-5-9 8-5-11

(B) After entering a judgment of responsible and setting a civil sanction and fees as specified in Section 8-5-9(A), the Civil Hearing Officer may order a compliance hearing and set a date for such hearing. Upon presentation of evidence and/or testimony by the City inspector at the compliance hearing that the violation(s) specified in the complaint has been abated, the Civil Hearing Officer may reduce all or a portion of the civil sanction commensurate with the cost borne by the defendant to achieve compliance, or the Civil Hearing Officer may vacate the previous judgment and dismiss the citation(s). If, a minimum of 7 calendar days before a scheduled compliance hearing, the Civil Hearing Officer receives both of the following items, then the Civil Hearing Officer may issue written orders commensurate with the authority given in this Section, to reduce civil sanctions and/or vacate the related judgment without holding the scheduled compliance hearing: (5062)

1. Written and notarized confirmation from the City inspector that the violation has been successfully abated, and (5062)

2. A written and notarized statement from the defendant describing the actions taken and the itemized costs borne to abate the violation. (5062)

If either item has not been received by the Civil Hearing Officer 7 calendar days before, then the compliance hearing shall take place as previously scheduled. (5062)

(C) The 36 month provision of paragraph (A) of this Section shall be calculated by the dates the violations were committed. The responsible party shall receive the enhanced sanction upon a finding of responsibility for any violation of this Chapter that was committed within 36 months of the commission of another violation for which the responsible party was convicted or was otherwise found responsible, irrespective of the order in which the violations occurred or whether the prior violation was civil or criminal. (5062)

(D) Each day in which a violation of this Chapter continues or the failure to perform any act or duty required by this Chapter or by the Civil Hearing Officer continues shall constitute a separate civil offense. (5062)

8-5-10: (RESERVED) 8-5-11: HABITUAL OFFENDER: (5062) (A) A person who commits a violation of this Chapter after previously having been found responsible for

committing civil violations of this Chapter on 3 separate dates and within a 36 month period, whether by admission, by payment of the fine, by default, or by judgment after hearing, shall be guilty of a Class 1 criminal misdemeanor. The Mesa City Prosecutor is authorized to file a Class 1 criminal misdemeanor complaint in the Mesa City Court against habitual offenders. For purposes of calculating the 36 month period under this paragraph, the dates of the commission of the offenses are the determining factor. (5062)

(B) Upon conviction of a violation of this Section, the court may impose a sentence authorized by the laws of the State of Arizona for a Class 1 misdemeanor, including incarceration not to exceed 6 months in jail or a fine not to exceed $2,500, exclusive of penalty assessments prescribed by law, or both. The court shall order a person who has been convicted of a violation of this Section to pay a fine of not less than $500 for each count upon which a conviction has been obtained and be placed on probation for up to 36 months.

City upon request, when such agent has reasonable cause to believe the person has committed a violation of this Chapter, is guilty of a misdemeanor. Evidence of identity under this Section shall consist of a person’s full name, residence address, and date of birth. (5062)

8-5-13: ABATEMENT: (5062) (A) In addition to or in lieu of filing a civil citation or criminal complaint, the City may serve a notice to abate

any violation of this Chapter. (5062)

(B) The notice to abate shall set forth the following information: (5062)

1. The responsible party has 30 calendar days from service of the notice to abate or correct the violation. (5062)

2. Identification of the property in violation by street address, if known, and if unknown, then by legal description of the property or by Maricopa County book, map, and parcel number. (5062)

4. Reinspection date and time. (5062)

5. Name, business address, and business phone number of the City inspector who issued the notice to abate. (5062)

6. A warning stating that if the violations are not corrected within the 30 calendar day period, the City may abate the problem itself or by private contractor, assess the responsible party for the cost of such abatement, and record a lien on the property for the assessment. (5062)

7. Hearing procedures. (5062)

8. Statement indicating that the 30 calendar day notice set forth in this Section shall not apply to emergency abatements pursuant to this Chapter. (5062)

(C) If the responsible party or other person served a notice to abate by the City pursuant to this Chapter fails to comply with such notice; the City may correct or abate the conditions subject to the notice if those conditions constitute a hazard. If the City corrects or abates those conditions, the City Manager or designee may prepare a verified statement as to the actual cost of correcting or abating the violation, including costs of inspection and other City-incurred costs associated with abating the violation. The statement shall be served pursuant to the Arizona Rules of Civil Procedure. That statement shall further set forth the following: (5062)

1. That the statement of costs is an assessment upon the lots and tracts of land from which the City corrected or abated the violation. (5062)

2. That the party has 15 calendar days from the date of delivery or mailing of the statement to pay. (5062

3. In the event payment is not received in 15 calendar days, the City will place a lien on the property in the amount of the assessment. (5062)

4. Appeal procedures. (5062)

(D) The notice to abate and the statement of abatement costs shall be served to the responsible party pursuant to the Arizona Rules of Civil Procedure. (5062)

8-5-14: REQUEST FOR ABATEMENT HEARING: (5062) The responsible party receiving a notice to abate under this Chapter or a statement of costs incurred

by the City in abating a hazard may appeal by requesting in writing a hearing and by serving such a request to the Development and Sustainability Department within 15 calendar days of service of the notice to abate or the statement of costs. The hearing shall be held before the Civil Hearing Officer as soon as practicable after the filing of the request. An appeal from final judgments of the Civil Hearing Officer may be taken pursuant to the Arizona Rules of Civil Procedure for special actions. If no written and timely request for hearing is made under this Section to the Development and Sustainability Department, then the notice of abatement or statement of costs is final and binding. (5062)

8-5-15: RECORDING AN ABATEMENT VIOLATION: (5062) The notice to abate and statement of costs shall run with the land. The City, at its sole option, may

record a notice to abate or statement of costs with the Maricopa County Recorder and thereby cause compliance by a person thereafter acquiring such property. When the property is brought into compliance, a satisfaction of notice to abate shall be filed with the Maricopa County Recorder. (5062)

8-5-16: EMERGENCY ABATEMENT: (5062) (A) If a situation presents an imminent hazard to life or public safety, the City may issue a notice to abate

directing the responsible party to immediately take such action as is appropriate to correct or abate the emergency described in the notice. In addition, the City may act immediately to correct or abate the emergency itself or may commence an action in Superior Court to enjoin the responsible party to abate the imminent hazard. In the event the City is unable to contact the responsible party despite reasonable efforts to do so, it in no way affects the City’s right under this Section to correct or abet the emergency itself. (5062)

(B) The City may recover its costs incurred in abating an imminent hazard under this Section in the same manner as provided for in Section 8-5-13(C). The responsible party may appeal the City’s emergency abatement action under this Section or the City’s statement of costs for an emergency abatement in the same manner as provided for in Section 8-5-14. (5062)

8-5-17: SUSPENSION OF CONSTRUCTION PERMIT OR LICENSE: (5062) Any construction permit or license issued by the City which authorizes work resulting in an alleged

violation of Section 8-5-2 or Section 8-5-3 of this Chapter may be suspended pending abatement of said violation or final resolution of a civil hearing of the matter. (5062)
