1.0 INTRODUCTION

This Operation, Maintenance, and Monitoring Plan (OMMP) describes the long-tem1

operation, maintenance, and monitoring activities to be conducted after completion of

remedial activities (RA) at the former Asarco Tacoma Smelter site (Site) On-Site

Containment Facility (OCF). The OMMP addresses operation, maintenance and monitoring

associated with the Tacoma Smelter Site OCF that is included in Operable Unit (OU) 02

(Asarco Tacoma Smelter - "Upland").

The final OCF cover was constructed during the fall of 2005. Asarco completed monitoring

of the OCF until the Site was purchased by Point Ruston in November of 2006. Point Ruston

assumed certain remaining obligations at the Site through execution of the Second

Amendment to the Consent Decree (October 2006). These obligations include continued

operation· and maintenance of the OCF as described in this OMMP.

This OCF OMMP has been prepared separately from the OMMP for the remainder of OU 02

(The Upland OMMP) since construction activities at the OCF have been completed prior to

completing RA in other areas within OU 02. The Upland OMMP addresses in detail the

monitoring requirements for groundwater and surface water, the process for data evaluation

and decisions, and reporting requirements that are applicable to the OCF OMMP. The OCF

OMMP refers to the Upland OMMP in these areas in order to provide consistency between

the two OMMPs. This OMMP should be used in conjunction with the Upland OMMP.

This OMMP is based on requirements described in the following documents:

• Record of Decision Commencement Bay Nearshore Tideflats Superfund Site

Washington (March 1995).

• Final Statement of Work for the Commencement Bay Nearshore/Tideflats

This OMMP is also based on input from the Asarco OMMP Task Force which convened

February through May 2001. This OMMP reflects the As-Built configuration of the OCF as

documented in the OCF as-built report (Womack & Associates, Inc., December 2005).

2.0 POST-RA OPERATIONS AND MAINTENANCE

The OCF will require O&M after RA to satisfy 40 CFR Sections 264.115-120 and 264.310.

The noted exception is that O&M for the OCF shall be indefinite rather than 30 years.

Requirements for a post-closure plan are outlined in 40 CFR Section 264.118. This OMMP

in conjunction with the Upland OMMP provides the post-closure plan for the OCF and the

other areas included in OU 02.

Figure 1 illustrates the as-built surface for the OCF cover and identifies locations for the

various components of the facility requiring monitoring and maintenance that are described

below. The OCF was constructed as a lined containment facility with a double composite

bottom liner system (see Figure 2) and a composite cover liner system. Detailed As-builts for

both the bottom and cover liner systems are presented in the OCF as-built report. Systems for

collection and removal of leachate and detection of leakage through the primary bottom

composite liner are incorporated in the OCF designs that are described in Section 2.1.1.

2.1 Operation and Maintenance Objectives

The ROD identifies standards from 40 CFR Part 264 that the OCF must comply with. Part

264 contains standards for owners and operators of hazardous waste treatment, storage, and

disposal facilities. Post-RA (post-closure) requirements are identified in Subpart G; Sections

264.115-120 and Subpart N; Section 264.310. Copies of the applicable sections from CFR 40

264 are attached in Appendix A. These sections require the following:

1) Provide a certification of closure (Sec. 264.115). Certification of closure will be

provided by Asarco, LLC and submitted to the regional administrator in

accordance with the requirements of this section;

2) Submit a survey plat (Sec. 264.116). The survey plat will be included with the

certification of closure;

3) Implement post-closure care including monitoring, maintenance, and reporting

(Sec. 264.117 and Sec. 264.31 O);


I I I I I I I II

I I I I I I I I I I I

OCF-OMMP

4) Submit a post-closure plan (Sec.264.118). Submittal of this OMMP fulfills this

requirement;

5) Submit post-closure notices (Sec. 264.119). Post closure notices will be submitted

within 60 days of certification of closure in accordance with the requirements of

this section; and

6) Submit certification of post-closure care (Sec. 264.120). Since the O&M period

for the OCF is indefinite a certification for the completion of post-closure care is

not applicable for the OCF. Annual reporting will therefore be used to document

the on-going operation, monitoring and maintenance activities for the OCF.

Specific O&M requirements as listed in Section 264.310 include:

I) Operate the leachate collection system. Refer to Section 2.1.1 below;

2) Maintain and monitor the leak detection system. Refer to Section 2.1.1 below;

3) Maintain the integrity and effectiveness of the final cover (settling, subsidence,

erosion, or other events). Refer to Section 2.1.3 below;

4) Prevent run-on and run-off from eroding the final cover. Refer to Section 2, 1.3

below;

5) Protect and maintain surveyed benchmarks used to comply with Sec. 264.309.

Refer to Section 2.1.5 below; and

6) Maintain a groundwater monitoring system. Refer to Section 3.1 below.

Due to the site location, an additional action is added that requires a thorough inspection after

a significant earthquake as described in Section 2.1. 7.

2.1.1 Leachate Collection and Leak Detection Systems

Liquid within the OCF can result from surface water allowed through the cover system along

with seepage resulting from precipitation contacting OCF backfill prior to constructing the

OCF cap. The leachate collection and removal system (LCRS) is the system between the

placed source area soils and the primary liner. It collects the liquid trapped on the primary

liner and pumps it to the leachate tank. The leak detection, collection and removal system


I I I I I

i I II

I I I I I I I I I I I I

OCF-OMMP

(LDCRS) is underneath the LCRS and is between the primary and secondary liners. It

collects liquid that occurs on the secondary liner.

The cross sections of the LCRS and LDCRS are shown on Figure 3. The LCRS and LDCRS

riser pipes are installed within the bottom liner system on the south OCF cell slope. Vault #1

located on the OCF berm provides access to the LCRS and LDCRS riser pipes. Pump

controls, monitoring ports, and instrumentation are located within Vault #1. Vault #2 is

located below the berm south of Vault #1 and includes the leachate storage tank and

instrumentation to monitor conditions within the vaults. Since the LCRS and the LDCRS are

essentially the same in construction, the O&M practices are generally combined herein.

For both the LCRS and LDCRS, the liquid collects in a sump located in the bottom of the

OCF liner where pumps equipped with fluid level sensors are located. Both pumps consist of

submersible wheeled SurePumps manufactured by EPG Companies (see Appendix B). The

pumps are controlled using level sensors and EPGs PumpMaster control panels located in

Vault #1. When the liquid level in either the LCRS or LDCRS sumps rises to 11 inches, the

pump will engage, evacuating the liquid. The pump will continue draining the liquid until the

level drops to the off setting for the pump. Operation and maintenance manuals for the EPG

pump system are presented in Appendix B.

The OCF cover system was completed during the fall of 2005. Prior to this time materials

backfilled in the OCF were exposed to rainfall. During the winter periods a temporary cover

system was used to collect rainwater in a sump located within the cell. The rainwater was

pumped from the sump and discharged to the on-site stormwater system. Damage to the

temporary cover typically occurred due to wind and other environmental factors and

therefore the temporary cover was not I 00 percent effective in preventing rain water from

entering the OCF backfill. For these reason leachate occurred in the LCRS during operation

and continues to occur since construction of the OCF cover system. After completion of the

OCF cover in September 2005, 325 gallons ofleachate per day were observed in the LCRS.

Since that time the flow has reduced to 225 gallons per day during July 2006. These


I I I I I I

'I I I I I I I I I I I I I

OCF-OMMP

observations indicate that significant leachate drainage will likely occur for the next several

years.

A 25,000 gallon temporary leachate storage tank was located adjacent to Vault #2 prior to

construction of the OCF cover system. This large tank was required to accommodate the

initial volume ofleachate that occurred during the period following construction of the cover.

In November 2006, Point Ruston replaced the 25,000 gallon temporary leachate storage tank

with a 5,000 gallon tank based on a reduction in leachate production (approx. 209 gal/day).

As drain down occurs, leachate production will continue to decline, the temporary tank will

be removed, and then leachate will then be stored using the 1,200 gallon leachate tank

located in Vault #2. At that time piping modifications will be required to connect to the tank

in Vault #2.

Biological growth in the LCRS and LDCRS pumps and flow systems is not anticipated due

to near anaerobic conditions. Normal O&M procedures for recording leachate flow data

should detect any operating abnormality that would require further investigation. The LCRS

and LDCRS will be inspected on a routine basis during monitoring to verify that they are

functioning properly. The leachate collection system has been equipped with a phone dialer

system to alert the operators of problems with the pumps, storage tanks, and conditions

within the vaults. If any abnormality were to occur, it would be identified during monitoring

or by the alarm system and the problem would be remedied. The pumping system is designed

so the pumps may be pulled if necessary and repaired or replacement pumps installed.

When necessary, the storage tank will be evacuated and leachate managed off-site by an off

site disposal contractor. Contact information for the disposal contractor is included in

Appendix C. Contact information included in Appendix C should be reviewed and updated

annually. Samples of the liquid will be taken from the storage tank to characterize the

leachate for disposal. Flow measurements of leachate collected in either the LCRS or the

LDCRS are provided by flow gauges installed within the Vault #1 piping. Readings are taken

periodically to determine the rate of leachate production and to monitor the volume of stored



OCF-OMMP

leachate. Leachate volume within the storage tank is carefully monitored to allow scheduling

for removal by the off-site disposal contractor.

Monitoring ofleachate storage volumes and operation of the LCRS and LDCRS is provided

using a system of phone dialers located in Vault #I. The system includes two phone dialers

and six alarm settings. The phone dialers will be set to contact a security monitoring

contractor in the event of a pump malfunction, flooding in the vaults, or when the leachate

storage tank requires pumping once leachate is routed to the collection tank located in the

lower vault. In the event of an alarm, the monitoring contractor will contact oversight and

maintenance personnel who will assess the reason for the alarm, provide any required

maintenance, schedule the disposal contractor to pump the leachate storage tank, and reset

the pump controls and monitoring system. Contact information for the security monitoring

contractor, maintenance personnel and operator are also included in Appendix C and should

be reviewed and updated annually.

The first dialer monitors the operation of the pumps in the LCRS and LDCRS and sends an

alarm when the pumps fail to operate. Pump operation is controlled by level sensors installed

on the pumps. The pumps are designed to turn on in response to level sensors located in the

LCRS and LDCRS sumps. An alarm occurs when the pump does not respond to levels

exceeding the pump on level. Dialer 1 also monitors the leachate level in the storage tank

located in Vault #2. When the tank level reaches 75 percent full an alarm is sent. In the event

that the 75 percent full alarm does not receive a response, a second alarm is sent when the

tank level reaches 90 percent full. In order to prevent overfilling the leachate storage tank and

spilling in vault #2, the LCRS and LDCRS pumps will not operate when the storage tank

exceeds the 90 percent full level. Leachate must be evacuated from the storage tank before

the system will resume pumping.

Dialer 2 monitors for flood conditions in Vaults 1 and 2, and an alarm is sent when flooding

occurs in the bottom of either vault. The wiring schematic for the monitoring/dialer system is

presented in Appendix B.

2.1.2 Response Action Plan

This Response Action Plan sets forth the actions that wiII be taken if the action leakage rate

for the OCF has been exceeded. The requirements for the Response Action Plan are specified

in 40 CFR Sections 264.302 and 304.

The action leakage rate is defined in 40 CFR Section 264.302 as the maximum design flow

rate that the LDCRS can remove without the fluid head on the bottom liner exceeding 1 foot.

The action leakage rate includes an adequate margin of safety that takes into account the

physical chai-actedstfcs of tffe applicatio~ settih~fof th-e system,-waste-and-liquid properties, - -

and determination of other sources and their contribution to the load of the leak detection

system.

The LDCRS collects liquid on the bottom (secondary) liner. If a significant amount of liquid

is found in the LDCRS, this is an indication that leakage is occurring between the primary

liner and the LDCRS. During construction and the first year after closure, the LDCRS may

collect some liquid that did not result from leaks in the top liner due to consolidation under

the weight of the OCF backfill, liquid can be pressed out of the soil liner and other materials

used to_construct the OCF. Monitoring completed prior to constructing the OCF cover

indicted LDC RS leakage rates exceeding 2 gallons per day prior to construction of the OCF

cover system. Since construction of the cover, flow rates less than 1 gallon per day have been

observed. During the period beginning during March 2006 no leachate flow has been

recorded from the LDCRS and the sump level sensor indicates that the level within the sump

is below the level that would activate the pump.

Analytical monitoring of leachate collected from the LDCRS sump has indicated the

presence of constituents that indicate communication between the LCRS and LDCRS. As

described above, leachate levels into the LDCRS have been minimal since construction of the

OCF cover when a reduction in flow to the LCRS occurred. This may suggest that any

communication between the two systems occurs in the primary liner above the elevation of

the LCRS sump.

OCF-OMMP

The volume collected in the LCRS and LDCRS will be measured. In accordance with 40

CFR Section 264.303, the volume of liquid collected in the LDCRS will be recorded at least

monthly after the final cover system is installed. If the fluid level in the LDCRS is less than

the pump operating level for two consecutive months, the amount of liquid collected will be

recorded at least quarterly. If the fluid level is less than the pump operating level for two

consecutive quarters, the amount of liquid collected will be recorded at least semi-annually.

If the pump operating level is exceeded at any point during the post-closure period, the

monitoring will return to a monthly schedule.

The volume of liquid collected in the LDCRS over the requisite period oftime will then be

converted to a daily flow rate (gallons per day for the 6.5 acre OCF). This value is then

compared with the action leakage rate of 2 gallons per day for the post-closure period.

When the action leakage rate is exceeded, the following actions will be taken to properly

document this exceedance and to remedy the situation (per 40 CFR Section 264.304):

I. Within 7 days of the determination of the exceedance, the Regional Administrator

will be notified in writing. During remaining remediation at the Site, the EPA

Project Manager will be notified of any exceedance and the Regional

Administrator notified at his direction.

2. Within 14 days of the detennination of the exceedance, a preliminary written

assessment will be submitted quantifying the amount of liquid, likely sources of

liquids, possible location, size, and cause of any leaks, and short-term actions

taken and planned.

3. Within the·next 16 days, the location, size, and cause of the leak will be

determined to the extent practicable. This includes assessing the source of the

liquids and determining the amount of liquid by source. To determine the source,

the liquid from the leak detection system sump will be analyzed and the physical

mobility and threat of the liquid and leak to the environment will be determined.

4. Any other short-term and longer-term action to be taken to mitigate or stop any

leaks will be detennined and planned.


I

I I I I

I I I I I I I

OCF-OMMP

5. Within 30 days after the notification that the action leakage rate has been

exceeded, the results of these determinations: location, size, and threat of the leak,

and any other actions planned; will be submitted in writing to the Regional

Administrator. This report will document why any or all of these assessments are

not required. Every month thereafter that the flow rate in the leak detection system

exceeds the action leakage rate, a report will be submitted to the Regional

Administrator delineating the RA taken and planned. During remaining

remediation at the Site, the report will be sent to the EPA Project Manager and the

Maintenance and inspection of the LCRS and LDCRS will be conducted in conjunction with

monitoring activities according to the schedule specified by the Response Action Plan.

Table 2-1 summarizes the maintenance and inspection program.

2.1.3 Final Cover

The top cover layer of the OCF is comprised of two layers. The top component is vegetation

designed to impede erosion, but which allows the surface run-off from major storm events.

The lower component consists of a minimum of two feet of soil capable of sustaining plant

species that will minimize erosion. Beneath the two foot soil layer, is a 12 inch thick biotic . '

layer designed to prevent intrusion of burrowing animals into the underlying low hydraulic

conductivity barrier layer. The barrier layer consists of a 40 mil HDPE geomembrane and

Geosynthetic Clay Liner (GCL). An irrigation system was installed within the soil cover

layer to sustain vegetation during the dry summer months. Details for construction of the

OCF cover system can be found in the OCF As-built report (Asarco, LLC, 2005).

The cover system was designed to fulfill requirements outlined by 40 CFR Sections 264.111

and 264.310, with the following objectives:

I. Minimize the need for further maintenance;

2. Control, minimize or eliminate, to the extent necessary to protect human

health and the environment, post-closure escape of Source Area soils and

demolition debris, hazardous constituents, leachate, contaminated run-off, or


-- I

hazardous waste decomposition products to the ground or surface waters or to

the atmosphere;

3. Provide long-term minimization of migration of liquids through the closed

OCF;

4. Function with minimum maintenance;

5. Promote drainage and minimize erosion or abrasion of the cover;

6. Accommodate settling and subsidence so that the cover's integrity is

maintained; and

·- 7. ·Have~a-permeability less titan orequal to·the permeability-of any-bottom liner - -

system or natural subsoil present.

The completed OCF cover will include the following design elements that will require

periodic inspection and maintenance:

• Vegetation and plantings consisting of grasses and shrubs may be planted along

the embankment crest area outside of the cover liner system and turf grasses

across the interior of the cell. Grasses on the OCF cap are provided to minimize

potential for erosion of the cover system.

• An irrigation system has been installed on the OCF cap to provide irrigation for

the turf during the dry summer months. The irrigation consists of a zoned system

of PVC pipes buried in the soil cover layer and sprinkler heads located across the

area. Appendix D presents a layout schematic for the OCF irrigation system.

• A drainage system is located in the anchor trench around the perimeter of the

OCF cover. The perimeter drain system is designed to collect and remove water

that infiltrates into the biotic layer and drains to the anchor trench around the

perimeter of the cover using perforated pipe. The perimeter drain system includes

a series of cleanouts along the entire perimeter of the OCF (see Figure 4). Each

segment of perforated pipe is connected to a manhole along the perimeter of the

OCF. The manholes are connected using a series of solid storm drain pipes that

discharge to the onsite storm water system on the eastern side of the 'OCF. The

perimeter drain system will be maintained to provide drainage for infiltration

water collected on the OCF cover liner.

I I I I

'I I I I I I I

OCF-OMMP

• A drainage swale is located on the east side of Bennett Street adjacent to the

western edge of the OCF cover and north of the proposed Bennett Street parking

area. The swale will provide drainage of surface runoff that occurs from the slope

below the shoulder of Bennett Street and will divert surface water to the north.

Erosion along the swale may compromise the integrity of the cover system and

obstructions within the swale could prevent runoff and result in ponding.

Inspection and maintenance of the swale are required to prevent erosion, ponding,

and to promote runoff.

Additionally, consolidation of source area fill in the OCF cell may result in minor differential

settlement that may require maintenance of the cap components identified above. The

inspection and maintenance program for the final cover system is outlined in Table 2-2. This

program includes maintenance and inspection items for the proposed Bennett Street Parking

Area. Construction of the parking area has not been completed prior to finalizing this

OMMP. Therefore the maintenance items identified for the parking area will need to be

reviewed and updated upon completion of the construction. An addendum to the OMMP may

be required and should be submitted in the annual report following the completion of.

2.1.4 Bennett Street Parking Area

A parking area is proposed over the southwest comer of The OCF that will be maintained by

the Town of Ruston. The parking area is to be constructed with a storm water collection

system that will drain to the storm drain located on Bennett Street, west of the OCF. The

parking area will include curbing and drain inlets to collect stormwater runoff. The

pavement, storm inlets, and curbing should be maintained to prevent stormwater runoff from

the parking area onto the OCF. All stormwater resulting from the parking area should be

diverted to the Bennett Street storm sewer. The OCF perimeter drain system his not been

designed to accommodate runoff from the parking area.

A 3H: 1 V fill slope will occur around the north and eastern sides of the parking area. The fill

should be maintained to prevent erosion and damage to the fill and potential impacts to the

underlying OCF cover system and OCF embankment slope at the southern edge of the

parking area.

Use of the Bennett Street Parking area should not include any activities including

construction, excavation or other impacts that could potentially jeopardize the OCF cover

system. Boring, trenching or any other excavation that may penetrate the OCF cover liner

system is prohibited. Load bearing elements that could result in a point load being applied to

the OCF cover liner system should not be allowed. Conditions within the Bennett Street

Parking area should be monitored annually to identify maintenance requirements.

2.1.5 Benchmarks

Maintenance of benchmarks must comply with 40 CFR Section 264.309 which requires the

identification of the following:

• Permanently surveyed benchmarks on a map that also shows the exact location

and dimension, including depth, of the OCF; and

• The contents of the OCF and the approximate location of the waste within the

cell.

Figures 1 and 2 present the contours for the OCF cover and bottom liner systems. The

volume between the cover and bottom liners consists of source area backfill. Two

benchmarks (OCF-BM-1 and OCF-BM-2) have been installed in the locations shown on

Figure 1 to provide a reference for the location and elevation of the OCF and source area

backfill. The benchmarks will be inspected once a year for damage and re-surveyed, if

necessary to confirm that the locations have not been damaged or removed. Table 2-3

identifies the maintenance and inspection schedule for benchmarks at the OCF.

2.1.6 Gas Monitoring

Gas generation may occur within the OCF as a byproduct of the decay of organic materials.

Gases of concern generally include carbon dioxide and methane. ·Migration of and

accumulation of gases from the OCF may occur in the LCRS layer and piping and in

confined spaces such as Vaults 1 and 2. Since gas generation causes a pressure buildup,

migration of gas in the OCF should follow the path of least resistance provided in the LCRS.

For this reason the LCRS forms a natural system for monitoring for gas migration. Both

Vaults 1 and 2 have been equipped with ventilation pipes and fans to increase air exchange

when the vault cover is open. The fans are switched on when the vault cover is opened.

Monitoring should be used to assess conditions within the vault before entering the confined

space.

Monitoring of methane levels within the vaults shall be performed prior to entering the vaults

for any maintenance, inspection, or other activity. Methane levels shall be monitored and

reported in conjunction with monitoring of the LDCRS pump rates as defined in the

Response Action Plan. Should elevated gas levels occur in the LCRS, the need for remedial

action will be addressed. The frequency and requirement for gas monitoring should be

reviewed based on measured levels.

2.1.7 Earthquake Damage

Should a significant seismic event occur in close proximity to the OCF, a post-earthquake

inspection will be completed to assess potential damage to the OCF embankment and cover

system. A two-tier inspection program will be used to allow for a rapid assessment of

earthquake damage. The first-tier will consist of a preliminary 1nspection that wiffoe -

followed up by a more detailed assessment and evaluation (second-tier). First-tier inspection

activities will be initiated within 48 hours of the seismic event. The need and schedule for

second-tier activities will be identified based on the results from the First-Tier inspection.

Table 2-4 identifies the requirements for potential earthquake inspection at the OCF.

3.0 OCF MONITORING

Post-RA monitoring for OU 02 requires sample collection from groundwater monitoring

wells, surface water stations including outfalls, and marine water sample locations. In order

to prevent duplication of monitoring requirements and potential for discrepancies between

the OMMPs, monitoring requirements for the OCF are described in the Upland OMMP. This

section of the OCF OMMP provides a general discussion of the monitoring requirements

associated with the OCF.

The post-RA environmental monitoring program addresses objectives described in the OU 06

Statement of Work (USEPA 2001) as well as long-term monitoring requirements for OU 02.

As a result, the post-RA monitoring program primarily addresses groundwater, surface water

(including surface water runoff and marine water) and marine sediments.

The post-RA environmental monitoring program is intended to monitor environmental

conditions and trends after RA is complete. However, some monitoring activities will not

begin until completion of RA in the areas surrounding the OCF.

3.1 Groundwater Monitoring Program

Groundwater beneath the OCF generally flows in a northeasterly direction toward

Commencement Bay, the ultimate groundwater discharge point. Some shallow groundwater

discharges to the surface as seeps and springs in the upper elevations of the site, specifically

along the steeper slopes on the southwest side of the site.

3.2 Groundwater Monitoring Locations and Wells

The OCF groundwater monitoring well network is designed to meet the requirements of 40

CRF 264.90 through 264.99. The proposed OCF specific monitoring well network consists of

five new monitoring wells (OCF-1 through OCF-5) constructed outside the perimeter of the

OCF berm. OCF-5 is planned to replace the abandoned MW-140. This network will provide

upgradient and down-gradient monitoring data for the OCF. Once constructed, the locations

will be documented in the Upland OMMP.



OCF-OMMP

Groundwater monitoring wells will be installed in accordance with (WAC I 73-160) using the

same well construction procedures for monitoring wells constructed during the RI and during

RA to help ensure groundwater data comparability. A detailed description of procedures for

monitoring well installation and development is provided in the Upland OMMP.

3.2.1 Groundwater Diversions and Controls

Groundwater diversions and controls included in OU 02 discharge to the surface water

conveyance system and therefore will be monitored as part of the surface water monitoring

program. Groundwater diversions (subdrains) are installed in the OCF subgrade. Outflow

from the subdrain system may occur from the HDPE pipe to the surface drainage on the east

side of the OCF embankment. The location of this pipe is illustrated on Figure 1.

3.3 GROUNDWATER MONITORING PARAMETERS

As described in the OU 6 ROD, at a minimum, post-RA groundwater monitoring will include

measurement of the following:

• static groundwater level;

• general water quality parameters (temperature, pH, conductivity, salinity, total

dissolved solids, total suspended solids, turbidity (field) , dissolved oxygen,

chloride, and sulfate);

• metals (arsenic, cadmium, copper, iron, manganese, nickel, lead, zinc); and

organics.

Additional analytical requirements will be addressed in the Upland OMMP.

The primary purpose for groundwater monitoring down gradient of the OCF is to determine

if there are inc·reases in metal concentrations that may be indicative, when combined with

data from the OCF leachate collection and leak detection system, of potential leaks. As such,

only dissolved metals will be measured in the OCF groundwater monitoring wells. A

complete list of groundwater monitoring constituents for the OCF monitoring wells is


I I I I I I I I I I I I I-I I

I I I I I

OCF-OMMP

presented in the Upland OMMP. OCF groundwater data collected from wells OCF-1

through OCF-5 will be analyzed as described in Section 4.1.

3.3.1 Groundwater Monitoring Frequency

Refer to the Upland OMMP for the Post RA monitoring frequencies.

3.3.2 Groundwater Sampling Methodology

Groundwater sample collection methods will follow established procedures previously and

presently used on the Site for RA Site-wide monitoring. These procedures are outlined in the

Upland OMMP and include Standard Operating Procedures (SOPs), and field and analytical

protocols. Prior to implementation of the sampling programs, a post-RA monitoring Quality

Assurance Project Plan (QAPP) will be prepared. The post-RA Quality Assurance Project

Plan will be based on the RA Quality Assurance Project Plan.

4.0 DATA EVALUATION AND DECISION PROCESS

4.1 OCF Assessment

The primary indicator of containment of contaminants within the OCF is the operational

monitoring associated with the OCF liner leakage detection systems described in Section

2.1.1. Evaluation of OCF environmental monitoring data collected from down-gradient wells

(OCF 1 through 5) must be conducted in consideration of the results from monitoring the

liner leakage system, down-gradient monitoring wells, and an evaluation of down-gradient

trends. Since water quality down-gradient of the OCF has been previously impacted from

upland source areas (primarily the Copper Refinery area) evaluation of water quality against

groundwater standards (MCLs or others) is not appropriate. As a result, the key indicators of

a groundwater condition associated with the OCF that may require supplemental activities

are:

1. Water quality results from operational monitoring of the OCF leakage detection

systems that indicate leakage through one or more of the liners may have or is

occurring.



OCF-OMMP

2. Significant leachate production requiring pumping from the LCRS sump.

3. The occurrence of leachate in the LDCRS sump in quantities sufficient to activate

the LDCRS pump.

4. Increasing down-gradient groundwater trends coupled with conditions 1, 2 and 3.

If these conditions occur, the hydraulic head within the LCRS and LDCRS may have resulted

in leakage through the secondary bottom liner components. This occurrence could be

correlated with down-gradient groundwater trends. Likewise, if leachate does not occur in the

LCRS and LDCRS sumps it is not likely that contaminants to groundwater are associated

with the OCF. In either case the evaluation and decision process defined in the Upland

OMMP should be followed to identify conditions at which additional groundwater controls

would be considered. Likewise, surface water impacts resulting from the OCF should not

result in exceedances in effluent limits established to meet Class AA marine water quality

criteria at the edge of approved mixing zones at the completion of RA.

5.0 REPORTING AND SCHEDULE

The Upland OMMP includes a schedule of O&M activities for OU 02 and identifies specific

reporting requirements that include the OCF and the surrounding areas. Section 2 of this

OMMP provides a summary of the maintenance and inspection schedule for the various

components of the OCF.

Monitoring of the LCRS and LDCRS shall be completed according to the schedule required

by the Response Action Plan presented in Section 2.1.2. Monitoring for ground water and

surface water related to the OCF will be completed in accordance to the schedule defined in

the Upland OMMP. The maintenance and inspection of other OCF components including the

OCF cover, Bennett Street Parking Area, OCF Benchmarks shall be shall be completed on an

annual schedule. In the event of a significant seismic event the Phase I and Phase 2

inspection described in Section 2.1. 7 shall be completed. Maintenance and data collected for

each of these activities must be documented and reported in the appropriate OMMP

deliverables identified above and in the Upland OMMP.

Appendix E includes standard report forms to document inspection, and maintenance of the

OCF. The following forms are included:

• LCRS and LDCRS Inspection Report, and

• OCF Cover Inspection Report

Forms have been prepared to provide the inspector a checklist of items requiring inspection

and or maintenance. The forms should be reviewed and updated as appropriate to address

changing conditions at the OCF and to provide a record of conditions across the OCF. Report

forms should be maintained as part of the permanent record for the facility and should be

used during preparation of the various OMMP reports.

§ 264.76 Unmanifested waste report. If a facility accepts for treatment,

storage. or disposal any hazardous waste from an off-site source without an accompanying rnanifest, or without an accompanying shipping paper as described in § 263.20(e)(2) of this chapter, and if the waste is not excluded from the manifest requirement by § 261.5 of this chapter, then the owner or operator must prepare and submit a single copy of a report to the Regional Administrator within fifteen days after receiving the waste. The unmanifested waste report must be submitted on EPA form 8700-138. Such report must be designated 'Unmanifested Waste Report' and include the following information:

(a) The EPA identification number, name, and address of the facility;

(b) The date the facility received the waste:

(c) The EPA identification number, name, and address of the generator and the transporter, if available:

(d) A description and the quantity of each unmanifested hazardous waste and facility received;

(e) The method of treatment, storage, or disposal for each hazardous waste;

(f) The certification signed by the owner or operator of the facility or his authorized representative: and

(g) A brief explanation of why the waste was unmanifested, if known.

[ Comment: Small quantities of hazardous waste are excluded from regulation under this part and do not require a manifest. Where a facility receives unmanifested hazardous wastes. the Agency suggests that the

§264.90

owner or operator obtain from each generator a certification that the waste qualifies for exclusion. Otherwise, the Agency suggests that the owner or operator file an unmanlfested waste report for the hazardous waste movement.]

Subpart F-Releases From Solid Waste Management Units

SOURCE: 47 FR 32350, July 26. 1982, unless otherwise noted.

§ 264.90 Applicability.

(a)(!) Except as provided in paragraph (b) of this section, the regulations in this subpart apply to owners or operators of facilities that treat, store or dispose of hazardous waste. The owner or operator must satisfy the requirements identified in paragraph (a)(2) of this section for all wastes (or constituents thereof) contained in solid waste management units at the facility, regardless of the time at which waste was placed in such units.

(2) All solid waste management units must comply with the requirements in §264.101. A surface impoundment, waste pile, and land treatment unit or landfill that receives hazardous waste after July 26, 1982 (hereinafter referred to as a "regulated unit") must comply with the requirements of §§ 264.91 through 264.100 in lieu of§ 264.101 for purposes of

183


§264.90

detecting, characterizing and responding to releases to the uppermost aquifer. The financial responsibility requirements of § 264. 101 apply to regulated units.

(b) The owner or operator's regulated unit or units are not subject to regulation for releases into the uppermost aquifer under this subpart if:

(1) The owner or operator is exempted under §264.1; or

(2) He operates a unit which the Regional Administrator finds:

(i) Is an engineered structure, (ii) Does not receive or contain liquid

waste or waste containing free liquids. (iii) Is designed and operated to ex

clude liquid, precipitation, and other run-on and run-off,

(iv) Has both inner and outer layers of containment enclosing the waste,

(v) Has a leak detection system built into each containment layer,

(vi) The owner or operator will provide continuing operation and maintenance of these leak detection systems during the active life of the unit and the closure and post-closure care periods, and

(vii) To a reasonable degree of certainty, will not allow hazardous constituents to migrate beyond the outer

· containment layer prior to the end of the post-closure care period.

(3) The Regional Administrator finds, pursuant to §264.280(d), that the treatment zone of a land treatment unit that qualifies as a regulated unit does not contain levels of hazardous constituents that are above background levels of those constituents by an amount that is statistically significant. and if an unsaturated zone monitoring program meeting the requirements of §264.278 has not shown a statistically significant increase in hazardous constituents below the treatment zone during the operating life of the unit. An exemption under this paragraph can only relieve an owner or operator of responsibility to meet the requirements of this subpart during the post-closure care period; or

(4) The Regional Administrator finds that there is no potential for migration of liquid from a regulated unit to the uppermost aquifer during the active life of the regulated unit (including the closure period) and the post-closure

40 CFR Ch. I (7-1-99 Edition)

care period specified under §264.117. This demonstration must be certified by a qualified geologist or geotechnical engineer. In order to provide an adequate margin of safety in the prediction of potential migration of liquid, the owner or operator must base any predictions made under this paragraph on assumptions that maximize the rate of liquid migration.

(5) He designs and operates a pile in compliance with §264.250(c).

(c) The regulations under this subpart apply during the active life of the regulated unit (including the closure period). After closure of the regulated unit, the regulations in this subpart:

(1) Do not apply if all waste, waste residues, contaminated containment system components, and contaminated subsoils are removed or decontaminated at closure:

(2) Apply during the post-closure care period under §264.117 if the owner or operator is conducting a detection monitoring program under§ 264.98; or

(3) Apply during the compliance period under §264.96 if the owner or operator is conducting a compliance monitoring program under § 264.99 or a corrective action program under §264.100.

(d) Regulations in this subpart may apply to miscellaneous units when necessary to comply with §§264.601 through 264.603.

(e) The regulations of this subpart apply to all owners and operators subject to the requirements of 40 CFR 270.1 (c)(7). when the Agency issues either a post-closure permit or an enforceable document (as defined in 40 CFR 270.l(c)(7)) at the facility. When the Agency issues an enforceable document, references in this subpart to "in the permit" mean "in the enforceable document."

(f) The Regional Administrator may replace all or part of the requirements of§§264.91 through 264.100 applying to a regulated unit with alternative requirements for groundwater monitoring and corrective action for releases to groundwater set out in the permit (or in an enforceable document) (as defined in 40 CFR 270.1 (c)(7)) where the Regional Administrator determines that:

(I) The regulated unit is situated among solid waste management units

184

,I I I I I I I I I I I I I I I I I I I


(or areas of concern), a release has occurred. and both the regulated unit and one or more solid waste management unit(s) (or areas of concern) are likely to have contributed to the release; and

(2) It is not necessary to apply the groundwater monitoring and corrective action requirements of§§ 264.91 through 264. 100 because alternative requirements will protect human health and the environment.

[47 FR 32350. July 26, 1982, as amended at 50 FR 28746, July 15, 1985; 52 FR 46963, Dec. 10. 1987; 63 FR 56733. Oct. 22. 1998]

§ 264.91 Required programs. (a) Owners and operators subject to

this subpart must conduct a monitoring and response program as follows:

(I) Whenever hazardous constituents under §264.93 from a regulated unit are detected at a compliance point under § 264.95, the owner or operator must institute a compliance monitoring program under §264.99. Detected is defined as statistically significant evidence of contamination as described in §264.98(f);

(2) Whenever the ground-water protection standard under §264.92 is exceeded, the owner or operator must institute a corrective action program under § 264.100. Exceeded is defined as statistically significant evidence of increased contamination as described in § 264.99(d);

(3) Whenever hazardous constituents under §264.93 from a regulated unit exceed concentration limits under §264.94 in ground water between the compliance point under § 264.95 and the downgradient facility property boundary. the owner or operator must institute a corrective action program under §264.100; or

(4) In all other cases. the owner or operator must institute a detection monitoring program under§ 264.98.

(b) The Regional Administrator will specify in the facility permit the specific elements of the monitoring and response program. The Regional Administrator may include one or more of the programs identified in paragraph (a) of this section in the facility permit as may be necessary to protect human health and the environment and will specify the circumstances under which

§264.93

each of the programs will be required. In deciding whether to require the owner or operator to be prepared to institute a particular program, the Regional Administrator will consider the potential adverse effects on human health and the environment that might occur before final administrative action on a permit modification application to incorporate such a program could be taken.

, § 264.92 Ground-water standard.

protection

The owner or operator must comply with conditions specified in the facility permit that are designed to ensure that hazardous constituents under § 264.93 detected in the ground water from a regulated unit do not exceed the concentration limits under § 264.94 in the uppermost aquifer underlying the waste management area beyond the point of compliance under § 264.95 during the compliance period under §264.96 .. The Regional Administrator will establish this ground-water protection standard in the facility permit when hazardous constituents have been detected in the ground water.

[53 FR 39728, Oct. 11. 19881

§ 264.93 Hazardous constituents.

(a) The Regional Administrator will specify in the facility permit the hazardous constituents to which the. ground-water protection standard of §264.92 applies. Hazardous constituents are constituents identified in appendix VIII of part 261 of this chapter that have been detected in ground water in the uppermost aquifer underlying a regulated unit and that are reasonably expected to be in or derived from waste contained in a regulated unit. unless the Regional Administrator has excluded them under paragraph (b) of this section.

(b) The Regional Administrator will exclude an appendix VIII constituent from the list of hazardous constituents specified in the facility permit if he finds that the constituent is not capable of posing a substantial present or potential hazard to human health or the environment. In deciding whether

§ 264.95 Point of compliance.

(a) The Regional Administrator will specify in the facility permit the point of compliance at which the groundwater protection standard of§ 264.92 applies and at which monitoring must be conducted. The point of compliance is a vertical surface located at the hydraulically downgradient limit of the waste management area that extends down into the uppermost aquifer underlying the regulated units.

(b) The waste management area is the limit projected in the horizontal plane of the area on which waste will be placed during the active life of a regulated unit.

(I) The waste management area includes horizontal space taken up by any liner, dike, or other barrier designed to contain waste in a regulated unit.

(2) If the facility contains more than one regulated unit, the waste management area is described by an imaginary line circumscribing the several regulated units.

187


§264.96

§ 264.96 Compliance period.

(a) The Regional Administrator will specify in the facility permit the compliance period during which the ground-water protection standard of § 264.92 applies. The compliance period is the number of years equal to the active life of the waste management area (including any waste management activity prior to permitting. and the closure period.)

(b) The compliance period begins when the owner or operator initiates a compliance monitoring program meeting the requirements of §264.99.

(c) If the owner or operator is engaged in a corrective action program at the end of the compliance period specified in paragraph (a) of this section. the compliance period is extended until the owner or operator can demonstrate that the ground-water protection standard of §264.92 has not been exceeded for a period of three consecutive years.

§ 264.97 General ground-water monitoring requirements.

The owner or operator must comply with the following requirements for any ground-water monitoring program developed to satisfy § 264.98, § 264.99, or § 264.100:

(a) The ground-water monitoring system must consist of a sufficient number of wells. installed at appropriate locations and depths to yield groundwater samples from the uppermost aquifer that:

(I) Represent the quality of background water that has not been affected by leakage from a regulated unit;

(i) A determination of background quality may include sampling of wells that are not hydraulically upgradient of the waste management area where:

(A) Hydrogeologic conditions do not allow the owner or operator to determine what wells are hydraulically upgradient; and

(B) Sampling at other wells will provide an indication of background ground-water quality that is representative or more representative than that provided by the upgradient wells; and

(2) Represent the quality of ground water passing the point of compliance.


(3) Allow for the detection of contamination when hazardous waste or hazardous constituents have migrated from the waste management area to the uppermost aquifer.

(b) If a facility contains more than one regulated unit, separate groundwater monitoring systems are not required for each regulated unit provided that provisions for sampling the ground water in the uppermost aquifer wi II enable detection and measurement at the compliance point of hazardous constituents from the regulated units that have entered the ground water in the uppermost aquifer.

(c) All monitoring wells must be cased in a manner that maintains the integrity of the monitoring-well bore hole. This casing must be screened or perforated and packed with gravel or sand, where necessary, to enable collection of ground-water samples. The annular space (i.e .. the space between the bore hole and well casing) above the sampling depth must be sealed to prevent contamination of samples and the ground water.

(d) The ground-water monitoring program must include consistent sampling and analysis procedures that are designed to ensure monitoring results that provide a reliable indication of ground-water quality below the waste management area. At a minimum the program must include procedures and techniques for:

(I) Sample collection: (2) Sample preservation and ship-

ment; (3) Analytical procedures: and (4) Chain of custody control. (e) The ground-water monitoring pro

gram must include sampling and analytical methods that are appropriate for ground-water sampling and that accurately measure hazardous. constituents in ground-water samples.

(f) The ground-water monitoring program must include a determination of the ground-water. surface elevation each time ground water is sampled.

(g) In detection monitoring or where appropriate in compliance monitoring. data on each hazardous constituent specified in the permit will be collected from background wells and wells at the compliance point(s). The number and kinds of samples collected to establish

188



background shall be appropriate for the form of statistical test employed, following generally accepted statistical principles. The sample size shall be as large as necessary to ensure with reasonable confidence that a contaminant release to ground water from a facility will be detected. The owner or operator will determine an appropriate sampling procedure and interval for each hazardous constituent listed in the facility permit which shall be specified in the unit permit upon approval by the Regional Administrator. This sampling procedure shall be:

(I) A sequence of at least four samples, taken at an interval that assures, to the greatest extent technically feasible, that an independent sample is obtained, by reference to the uppermost aquifer's effective porosity, hydraulic conductivity, and hydraulic gradient, and the fate and transport characteristics of the potential contaminants, or

(2) an alternate sampling procedure proposed by the owner or operator and approved by the Regional Administrator.

(h) The owner or operator will specify one of the following statistical methods to be used in evaluating groundwater monitoring data for each hazardous constituent which, upon approval by the Regional Administrator, will be specified in the unit permit. The statistical test chosen shall be conducted separately for each hazardous constituent in each well. Where practical quantification limits (pql"s) are used in any of the following statistical procedures to comply with §264.97(i)(S), the pql must be proposed by the owner or operator and approved by the Regional Administrator. Use of any of the following statistical methods must be protective of human health and the environment and must comply with the performance standards outlined in paragraph (i) of this section.

(I) A parametric analysis of variance (ANOVA) followed by multiple comparisons procedures to identify statistically significant evidence of contamination. The method must include estimation and testing of the contrasts between each compliance well's mean and the background mean levels for each constituent.

§264.97

(2) An analysis of variance (ANOVA) based on ranks followed by multiple comparisons procedures to identify statistically significant evidence of contamination. The method must include estimation and testing of the contrasts between each compliance well's median and the background median levels for each constituent.

(3) A tolerance or prediction interval procedure in which an interval for each constituent is established from the distribution of the background data, and the level of each constituent in each compliance well is compared to the upper tolerance or prediction limit.

(4) A control chart approach that gives control limits for each constituent.

(5) Another statistical test method submitted by the owner or operator and approved by the Regional Administrator.

(i) Any statistical method chosen under § 264.97 (h) for specification in the unit permit shall comply with the following performance standards, as appropriate:

(I) The statistical method used to evaluate ground-water monitoring data shall be appropriate for the distribution of chemical parameters or hazardous constituents. If the distribution of the chemical parameters or hazardous constituents is shown by the owner or operator to be inappropriate for a normal theory test, then the data should be transformed or a distribution-free theory test should be used. lf the distributions for the constituents differ, more than one statistical method may be needed.

(2) If an individual well comparison procedure is used to compare an individual compliance well constituent concentration with background constituent concentrations or a ground-water protection standard, the test shall be done at a Type I error level no less than 0.01 for each testing period. If a multiple comparisons procedure is used, the Type I experimentwise error rate for each testing period shall be no less than 0.05; however, the Type l error of no less than 0.01 for individual well comparisons must be maintained. This performance standard does not apply to tolerance intervals, prediction intervals or control charts.

189


§264.98

(3) If a control chart approach is used to evaluate ground-water monitoring data. the specific type of control chart and its associated parameter values shall be proposed by the owner or operator and approved by the Regional Administrator if he or she finds it to be protective of human health and the environment.

(4) If a tolerance interval or a prediction interval is used to evaluate groundwater monitoring data, the levels of confidence and, for tolerance intervals, the percentage of the population that the interval must contain. shall be proposed by the owner or operator and approved by the Regional Administrator if he or she finds these parameters to be protective of human health and the environment. These parameters will be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

(5) The statistical method shall account for data below the limit of detection with one or more statistical procedures that are protective of human health and the environment. Any practical quantification limit (pql) approved by the Regional Administrator under § 264.97(h) that is used in the statistical method shall be the lowest concentration level tha can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions that are available to the facility.

(6) If necessary, the statistical method shall include procedures to control or correct for seasonal and spatial variability as well as temporal correlationin the data.

(j) Ground-water monitoring data collected in accordance with paragraph (g) of this section including actual levels of constituents must be maintained in the facility operating record. The Regional Administrator will specify in the permit when the data must be submitted for review.

Subpart N-Landfills

SOURCE: 47 FR 32365, July 26, 1982, unless otherwise noted.


The regulations in this subpart apply to owners and operators of facilities that dispose of hazardous waste in landfills, except as § 264.1 provides otherwise.

§ 264.301 Design and operating requirements.

(a) Any landfill that is not covered by paragraph (c) of this section or § 265.301 (a) of this chapter must have a liner system for all portions of the landfill (except for existing portions of such landfill). The liner system must have:

(I) A liner that is designed, constructed, and installed to prevent any migration of wastes out of the landfill to the adjacent subsurface soil or ground water or surface water at anytime during the active life (including the closure period) of the landfill. The liner must be constructed of materials that prevent wastes from passing into the liner during the active life of the facility. The liner must be:

(i) Constructed of materials that have appropriate chemical properties and sufficient strength and thickness to prevent failure due to pressure gradients (including static head and external hydrogeologic forces). physical contact with the waste or leachate to which they are exposed, climatic conditions, the stress of installation, and the stress of daily operation;

§264.301

(ii) Placed upon a foundation or base capable of providing support to the liner and resistance to pressure gradients above and below the liner to prevent failure of the liner due to settlement, compression. or uplift; and

(iii} Installed to cover all surrounding earth likely to be in contact with the waste or leachate; and

(2) A leachate collection and removal system immediately above the liner that is designed, constructed, maintained, and operated to collect and remove leachate from the landfill. The Regional Administrator will specify design and operating conditions in the permit to ensure that the leachate depth over the liner does not exceed 30 cm (one foot). The leachate collection and removal system must be:

(i) Constructed of materials that are: (A) Chemically resistant to the waste

managed in the landfill and the leachate expected to be generated; and

(8) Of sufficient strength and thickness to prevent collapse under the pressures exerted by overlying wastes, waste cover materials. and by any equipment used at the landfill; and

(ii) Designed and operated to function without clogging through the scheduled closure of the landfill.

(b) The owner or operator will be exempted from the requirements of paragraph (a) of this section if the Regional Administrator finds, based on a demonstration by the owner or operator, that alternative design and operating practices, together with location characteristics. will prevent the migration of any hazardous cons ti tucnts (see § 264.93) into the ground water or surface water at any future time. In deciding whether to grant an exemption, the Regional Administrator will consider:

(I) The nature and quantity of the wastes;

(2) The proposed alternate design and operation;

(3) The hydrogeologic setting of the facility. including the attenuative capacity and thickness of the liners and soils present between the landfill and ground water or surface water; and

(4) All other factors which would influence the quality and mobility of the leachate produced and the potential for it to migrate to ground water or surface water.

291


§264.301

{c) The owner or operator of each new landfill unit on which construction commences after January 29. 1992. each lateral expansion of a landfill unit on which construction commences after July 29. 1992, and each replacement of an existing landfill unit that is to commence reuse after July 29. 1992 must install two or more liners and a leachate collection and removal system above and between such liners. "Construction commences" is as defined in § 260. IO of this chapter under "existing facility".

{I) (i) The liner system must include: (A) A top liner designed and con

structed of materials (e.g., a geomembrane) to prevent the migration of hazardous constituents into such liner during the active life and post-closure care period; and

(B) A composite bottom liner. consisting of at least two components. The upper component must be designed and constructed of materials (e.g., a geomembrane) to prevent the migration of hazardous constituents into this component during the active life and post-closure care period. The lower component must be designed and constructed of materials to minimize the migration of hazardous constituents if a breach in the upper component were to occur. The lower component must _be constructed of at least 3 feet (91 cm) of compacted soil material with a hydraulic conductivity of no more than lxI0- 7

cm/sec. (ii) The liners must comply with

paragraphs (a){I) (i). (ii). and (iii) of this section.

(2) The leachate collection and removal system immediately above the top liner must be designed. constructed. operated. and maintained to collect and remove leachate from the landfill during the active life and post-closure care period. The Regional Administrator will specify design and operating conditions in the permit to ensure that the leachate depth over the liner does not exceed 30 cm (one foot). The leachate collection and removal system must comply with paragraphs (3)(c) (iii) and (iv) of this section.

§ 264.302 Action leakage rate.

(a) The Regional Administrator shall approve an action leakage rate for surface impoundment units subject to § 264.301 (c) or (d). The action leakage rate is the maximum design flow rate that the leak detection system (LDS) can remove without the fluid head on the bottom liner exceeding I foot. The action leakage rate must include an adequate safety margin to allow for uncertainties in the design (e.g., slope, hydraulic conductivity, thickness of drainage material), construction, operation, and location of the LOS, waste and leachate characteristics, I ikelihood and amounts of other sources of

293


§264.303

liquids in the LOS. and proposed response actions (e.g .. the action leakage rate must consider decreases in the flow capacity of the system over time resulting from siltation and clogging, rib layover and creep of synthetic components of the system, overburden pressures, etc.).

(b) To determine if the action leakage rate has been exceeded, the owner or operator must convert the weekly or monthly flow rate from the monitoring data obtained under § 264.303(c). to an average daily flow rate (gallons per acre per day) for each sump. Unless the Regional Administrator approves a different calculation, the average daily flow rate for each sump must be calculated weekly during the active life and closure period, and monthly during the post-closure care period when monthly monitoring is required under § 264.303(c).

(57 FR 3490, Jan. 29, 1992]

§ 264.303 Monitoring and inspection. (a) During construction or installa

tion, liners (except in the case of existing portions of landfills exempt from § 264.301 (a)) and cover systems (e.g., membranes, sheets, or coatings) must be inspected for uniformity, damage. and imperfections (e.g.. holes. cracks, thin spots, or foreign materials). Immediately after construction or installation:

(I) Synthetic liners and covers must be inspected to ensure tight seams and joints and the absence of tears, punctures, or blisters; and

(2) Soil-based and admixed liners and covers must be inspected for imperfections including lenses, cracks. channels, root holes, or other structural non-uniformities that may cause an innease in the permeability of the liner or cover.

(b) While a landfill is in operation, it must be inspected weekly and after storms to detect evidence of any of the following:

(I) Deterioration, malfunctions. or improper operation of run-on and runoff control systems;

(2) Proper functioning of wind dispersal control systems, where present; and

(3) The presence of leachate in and proper functioning of leachate collec-


tion and removal systems, where present.

(c)(I) An owner or operator required to have a leak detection system under § 264.301 (c) or (d) must record the amount of liquids removed from each leak detection system sump at least once each week during the active life and closure period.

(2) After the final cover is installed, the amount of liquids removed from each leak detection system sump must be recorded at least monthly. If the liquid level in the sump stays below the pump operating level for two consecutive months, the amount of liquids in the sumps must be recorded at least quarterly. If the liquid level in the sump stays below the pump operating level for two consecutive quarters, the amount of liquids in the sumps must be recorded at least semi-annually. If at any time during the post-closure care period the pump operating level is exceeded at units on quarterly or semiannual recording schedules, the owner or operator must return to monthly recording of amounts of liquids removed from each sump until the liquid level again stays below the pump operating level for two consecutive months.

(3) "Pump operating level" is a liquid level proposed by the owner or operator and approved by the Regional Administrator based on pump activation ievel, sump dimensions, and level that avoids backup into the drainage layer and minimizes head in the sump.

§ 264.304 Response actions.

(a) The owner or operator of landfill units subject to §264.30!(c) or (d) must have an approved response action plan before receipt of waste. The response action plan must set forth the actions to be taken if the action leakage rate has been exceeded. At a minimum, the response action plan must describe the actions specified in paragraph (b) of this section.

(b) lf the flow rate into the leak detection system exceeds the action leakage rate for any sump. the owner or operator must:

(I) Notify the Regional Administrator in writing of the exceedence within 7 days of the determination:

(2) Submit a preliminary written assessment to the Regional Administrator within 14 days of the determination, as to the amount of liquids, likely sources of liquids, possible location, size, and cause of any leaks, and shortterm actions taken and planned:

(3) Determine to the extent practicable the location, size, and cause of any leak:

(4) Determine whether waste receipt should cease or be curtailed, whether any waste should be removed from the unit for inspection, repairs, or controls, and whether. or not the unit should be closed;

(5) Determine any other short-term and longer-term actions to be taken to mitigate or stop any leaks; and

(6) Within 30 days after the notification that the action leakage rate has been exceeded, submit to the Regional Administrator the results of the analyses specified in paragraphs (b)(3), (4). and (5) of this section, the results of actions taken, and actions planned. Monthly thereafter, as long as the flow rate in the leak detection system exceeds the action leakage rate, the owner or operator must submit to the Regional Administrator a report summarizing the results of any remedial actions taken and actions planned.

(c) To make the leak and/or remediation determinations in paragraphs (b)(3). (4), and (5) of this section. the owner or operator must:

(l)(i) Assess the source of liquids and amounts of liquids by source,

(ii) Conduct a fingerprint, hazardous constituent, or other analyses of the liquids in the leak detection system to identify the source of liquids and possible location of any leaks, and the hazard and mobility of the liquid; and

(iii) Assess the seriousness of any leaks in terms of potential for escaping into the environment; or

(2) Document why such assessments are not needed.

IMPORTANT NOTICE:

EPG SUREPUMP™ SUMP DRAINER VENT TUBE/CHECK VAL VE

INSTALLATION INSTRUCTIONS

June 1995

EPG's patented sump drainer* enables the use of a stainless steel and Teflon submersible pump in applications that would normally require a sump type pump.

Critical to the operation of the sump drainer is the installation of the vent tube and air check valve. The vent tube/ check valve assembly has 2 functions. As the sump drainer fills with fluid the vent tube assembly"allows air, trapped in side of the sump drainer to escape - allowing the sump drainer to completely fill with fluid. When the sump drainer pump starts, the vent assembly closes, allowing the pump to draw water through the screen at the opposite end of the sump drainer. The closed check valve enables the pump to continue pumping even though the fluid level in the sump is below the normal intake of the pump.

The vent check valve must be set at no less than a 15° angle above the horizon for it to operate correctly. The vent tube may be tied off to the pump discharge line. The vent check valve will operate correctly even if submerged.

Installation

Refer to Figure 1 for help in completing this procedure.

1. Slip the free end of the plastic vent tube onto the adapter on the top of the sump drainer.

2. Verify the open end of the check valve is labeled "VAC".

3. As you lower the sump drainer into the sump, uncoil the vent tube and fasten it to the discharge pipe. We recommend you keep the check valve above the fluid level. The check valve will work if it is submerged, but can foul with particles in the fluid.

Note: Please refer to Table B for list of tools needed for disassembly, testing and assembly.

March 1993

1. Place the pump on a suitable work surface with blocks to prevent the pump from rolling. Remove the vent tube by pulling straight out from the top.

[ In cold weather it is better to unscrew the vent hose barb adaptor with J

tube attached rather than try to pull the tube off the hose barb.

2. Unscrew the cord restraint nuts and pull inserts out about two(2) feet along the mcror lead and level sensor lead. Loosen the insert from the wires so they are free to move through the cord restraint.

3. Mark the alignment of the tube and top (check for factory alignment marks). Cemer punch new marks in top and tuoe if factory marks can not be found. The alignment marks will make reassembly easier. ·

4. Remove capscrews (3) that secure the tube to the top and carefully pull the top, with pump and motor attached, out of the tube. DO NOT HAMMER, PRY, OR POUND ON TUBE OR TOP. Allow the sensor leadwire to slide through the cord restraint.

5. Remove the socket head setscrews (3) from the level sensor housing on me bottom of the tube. Carefully pull the level sensor up and out from the bottom of the tube. Carefully remove the sensor leadwire by pulling the controller end back through the top. Cover the end of the sensor leadwire with tape to prevent moisture and dirt from entering. If sensor is unused or put into Storage, remove the dryer from the controller and install on end of vent tube during storage period.

6. Remove the nuts (4) that secure the motor to the pump and pull the motor from the pump.

NOTE

DO NOT REMOVE TIIE MOTOR LEAD FROM THE MOTOR UNLESS IT WILL. · BE REPLACED WITH A NEW LEAD. It is recommended that a new motor lead be.

used whenever the old lead is removed from the motor because of possible · damage to die lead or disrortion of the rubber seal that may prevent resealing.

7. Unscrew the motor lead nut from the motor. Work the lead back and forth to loosen seal and unplug the lead from the motor connector. Remove the lead by pulling the controller end back through the top ..

8. Unscrew the pump assembly from the top using cloth strap wrenches to prevent damage to the metal surfaces. · ·

EPG LEVELMASTER™ SUBMERSIBLE LEVEL SENSOR SYSTEM

\_ 0,1,Q•

GENERAL FEATURES

* Ease of Installation LevelMaster is designed specifically to work with the EPG SurePump™, but it's durability, accuracy and weight make it the logical choice for stand alone applications. The chemical resistant lead wire contains a vent tube for atmospheric pressure compensation.

* Ranges Available 0 to 5 through 0-50 PSIG models are available. Please call for special needs.

TRANSMITTER FEATURES:

* Accuracy LevelMaster bas built-in temperature compensation as well as precise calibration giving an accuracy of ±1.0%. at ambient temperature and a combined repeatability and hysteresis error of ±.125%.

* Fully Submersible LevelMaster transmitter is fully submersible in any liquid compatible with 316 stainless steel and the chemical resistant polyurethane cable jacket. Leve!Master sensor is designed for submergence at depths greater than operating level without sustaining damage. For more severe service consult the factory.

* Superior Noise Immunity . Designed for heavy duty use in hostile environments, Leve!Master gives outstanding n~ise immunity. Unlike transducers, whose signals may be distorted by outside interference, the Levell\llaster utilizes a conditioned compensated 4-20mA output to maximize signal strength and accuracy. The sensor also features a shielded lead to help prevent signal disruption from outside sources.

. USER'S GUIDE

Submersible Level Sensor for Liquid Level Measurement

Congratulations on your purchase of an EPG Companies pressure transmitter. Our precision measurement devices are built to exacting standards. Before shipping, all units pass rigorous inspection by our Quality Assurance program.

Please take a few moments to read this brief user's manual to fully acquaint yoursel( with the characteristics, features, and benefits of your EPG transmitter.

Future orders may be placed by calling our Applications Support and Order Hotline at 800-443-7426. Call (800) 762-8418 for warranty repair service.

Characteristics of EPG Companies Transducersffransmitters

All EPG transducers incorporate our isolated diaphragm sensors, which are specifically· designed for use with hostile fluids and _gases. These sensors utilize a silicon pressure. cell that has been fitted into a stainless steel package with a stainless steel banier diaphragm. This sensor assembly is housed in a rugged 316 SS case, which provides for a variety of pressure inputs

Our devices feature high performance internal signal conditioning. Standard output is 4.to 20 mA. All units have surge and reverse polarity protection.

For your convenience and ease of use in the field, all EPG transmitters are permanently etched with our logo & name, wiring information, part number (PIN), serial number (SIN), date of manufacture (DOM), range, excitation, and output.

All EPG transmitters are designed for ru._gged use. However, care should be taken to protect these devices from overpressure and sharp impact. When lowering submersible pressure· transmitters into a liquid, penetrate the surface slow!Y and only to the depth necessary. Avoid dropping the unit from above the surface. All transmitters can be cleaned by ri~sing them in mild detergent. Do not pressure wash.

Warranty

EPG Companies warrants its products against defects in material and workmanship for 12 months from date of shipment. Products not subjected to misuse will be repaired or replaced. THE FOREGOING IS IN LIEU OF ANY OTHER EXPRESSED OR IMJ>LIED . WARRANTIES. EPG Companies reserves the right to make changes to any product herein and assumes no liability arising out of the applications or use of any product or circuit described.

D0100-4 Vent Filter & Wate_r Vapor Trap

The DDI00-4 is a replaceable vent tube dehumidifier intended for use with our submersible pressure transmitters. This device is specifically designed to protect sensitive electronic components from mildew, corrosion, rust, and other forms of deterioration while at the same time preventing the formation of a liquid column.

Vent filters should be changed when they are 85% spent. Do not remove the old filter until a new one is available. The number one failure mode is moisture and corrosion damage due to lack of maintenance of the vent filter.

The DD 100-4 connects to the existing vent tube as it exits the cable at the junction box via a tube. The unbreakable acrylic drying tube is 4 inches in length and 3/4 inches in diameter. Inserted in each pull-off molded polypropylene drying tube end cap is a 20 micron · polypropylene filter.

The drying tube is filled with an indicating desiccant (drying agent). The maximum flow rate through the drying tube is 300 cubic centimeters per minute, more than sufficient to allow the transmitter to respond to barometric changes. As air passes through the drying tube, moisture is absorbed by the desiccant. The desiccant changes from blue to a rose red as its dryirig · . capacity becomes diminished.

The desiccant can be rejuvenated after normal use by spreading it in a layer one granule· deep and heating for one hour at 205°C (400°F). The heating temperature is very important for if it is lower than 205°C (400°F) the desiccant will not rejuvenate. Alternatively, if the desiccant is overheated, the crystal structure may be altered and render the desiccant permanently inactive. Alternatively, spare vent filters can be ordered by calling 800-443-7426. The DD 100~4 _vent filter and water vapor trap can be exposed to air, industrial gases, refrigerants, organic liquids, and solvents. It should not, however, be used when ammonia is present. · · ·

INSTALLATION NOTES AND TROUBLESHOOTING

BACKGROUND: Numerous installations of the EPG LevelMaster system have proven its long-te~ reliability. The majority of malfunctions of the LevelMaster system are the result of improper installation and handling of the pressure transmitter sensor. During new installations, be certain to check for any shipping damage, loose controller connections or parts that may have come loose during shipment. .

A. IMPROPERLY INSTALLED SENSOR VENT DRYER. The sensor vent tube, a small hollow tube in the center of the Ieadwire, must be connected to the dryer cylinder in the controller to prevent moisture from entering and damaging the sensor. The vent tube must be open to the dryer to allow atmospheric pressure equalization.

B. DAMAGED/CUT/CRUSHED SENSOR LEADWIRES. Most failures at startup or shortly thereafter are the result of damaged sensor leadwires. If the leadwire outer shield is damaged, moisture can enter the conductors causing intermittent or complete failure.

USE CARE WHEN INST ALLING THE LEADWIRE during pwnp instalJation. Protect the Jeadwire with sleeving or plastic ~bing to prevent cutting or gouging the insulation when feeding the leadwire through or over any sharp or jagged edges.

C. IMPROPER SENSOR LEADWIRE CONNECTION. Check the schematic drawing shipped with the pump controller to assure the sensor BLUE (BLACK on some models) wire is connected to the minus(-) controller terminal and the sensor WHITE (RED on some models) wire is connected to the plus(+) controller terminal.

D. PHYSICAL ABUSE/DAMAGE OF THE SENSOR. Do not attempt to disassemble the sensor. Do not strike or hammer against a hard surface. - THE WARRANTY JS VOID IF THE PROBE HAS BEEN DISASSEMBLED, DENTED OR CRUSHED.

S3070-PT TRANSDUCER SIMULATOR Operation

December 1999

The model 3070-PT Transducer Simulator is a device designed for the express purpose of testing an EPG LevelMaster™ level controller circuit while temporarily bypassing the existing level sensor. In the ''Run" (nomial operation) mode liquid level in the sump applies pressure on the level sensor. The sensor converts that force into an electrical signal. The electrical signal jg transmitted by the sensor cable to the level meter where it is converted into a liquid level display.

The "Test" mode simulates a level sensor signal. Rotating the potentiometer changes the electrical signal forcing the system to function as if a level sensor were in the circuit. Varying the electrical signal changes the level meter display in the same manner in which the level sensor signal would effect the system. By turning the simulator knob slowly clockwise from top to bottom the meter will display each set point such as start, stop and alarms. With the toggle switch turned back to the ''Run" position the potentiometer is removed from the circuit and the level sensor controls according to the set points. Meter values register actual liquid level.

"CAUTION", care must be taken when using this device in "Test" mode to avoid damaging the motor by running it dry. In normal test mode the pump switches should be off

S3070-PT TRANSDUCER SIMULATOR TEST PROCEDURE

December 1999

1. When the toggle switch is in the "Run" position the controls should function normally. 2. When the toggle switch is in the "Tesf'_position (pressure transducer temporarily removed from

he control circuit) the level meter should display the liquid level. By turning the simulator knob slowly clockwise from top to bottom the meter will display each set point such as start, stop, and alarms. Care must be taken when using this device in the "Test" mode to avoid damaging the motor by running it dry. In normal test mode the _purp.p switches should be off

3 .. Make sure that the potentiometer has full travel (270 degrees maximum) in both clockwise and counter-clockwise directions.

4. Make sure that all of the wires on the rear ofthe simulator (wires 200,201,202,203) are connected in the proper position.

5. Replace the transducer simulator if it does not function as described above.

TYPE "SR" PVC SUCTION AND TRANSFER HOSE

APPLICATIONS: Trash pump hose, irrigation pumping, slurry handling, and leachate transfer in landfills.

FEATURES: Heavy duty PVC suction and transfer hose. Superior vacuum rating. Smooth bore eliminates material build-up. Rigid polyvinyl chloride, in general, shows excellent resistance to acids, alkalis, aqueous solutions of salts, and many organic solvents and oils. Plasticized PVC is attacked by certain chlorinated hydrocarbons, aromatics, esters, ketones, aldehydes, phe1!ols, and strong oxidizing agents.

This chemical resistance is based on tests of specimens conducted by completely submerging the hose sample in the listed chemical or reagent. In critical applications, it is suggested that greater reliance be placed on actual field experience or that testing be performed under conditions of stress, exposure, temperature and duration which can be related to the anticipated application. ·
