Where have we been?Where have we been?

Why Operation and Maintenance?Why Operation and Maintenance?

Currently more than 259 systems in operation with a public investment of over $77 million

Experience has shown that passive systems have routine operational needs, have expected and often unexpected major maintenance requirements and will eventually need to be replaced

Failure to provide for OMR will result in the loss of restored water resources and public investment

TermsTerms Construction: Cost to build the treatment system. O & M: Operation and maintenance activities including

inspections, sampling, sample analysis, flushing, scheduled maintenance, and non-catastrophic unscheduled maintenance.

R: Single replacement of the system. Projected costs may approach original construction costs.

O, M & R: Combined operation, maintenance and replacement costs.

Guiding Principles for Projects in PennsylvaniaGuiding Principles for Projects in Pennsylvania

True Sustainable Operation, Maintenance & Replacement is based on LOCAL COMMUNITY

Ownership & InvolvementThe goal is a system of healthy

INTERDEPENDENCE & PARTNERSHIP between

government and local sponsors

OMR Support StrategyOMR Support Strategy

Local Sponsors provide routine operation and maintenance

Maintenance needs assisted by local industry, local government and/or BAMR construction staff

DEP provides funding for more significant maintenance and eventual system replacement

Where are we now?Where are we now?

Present Status:Present Status: GG projects now require OMR plans as a deliverable GG project applications that adequately address OMR receive a

higher score, particularly when non-government sources are utilized Local sponsors are expected to provide routine operations GG has an OMR project-type category and provides funding for

maintenance and replacement on a competitive scoring, annual grant, basis

WPCAMR has received a grant to fund lab analyses WPCAMR has received 2 Quick Response grants and has applied

for a third in the 2008 grant round BAMR has put together OMR task force to evaluate existing BAMR

passive treatment systems

WPCAMR Lab Analysis GrantWPCAMR Lab Analysis Grant $166,000 grant provides funding for lab analysis by

local labs: Mahaffey Lab (Grampian) & G&C Lab in Summerville

Currently covering 7 counties: Allegheny, Armstrong, Butler, Clarion, Clearfield, Indiana and Jefferson

Requires an OMR plan Has been underutilized Grant expired 6/30/08; an extension has been

requested but no decision has been made yet

WPCAMR Quick Response GrantWPCAMR Quick Response Grant Started in 2006 A mechanism to quickly provide GG funds to local sponsors when

failure to act quickly will likely result in serious environmental consequences or will contribute to further damage of a project

Current grant has a remaining balance of $189,000 and has been extended to 6/30/09

2007 grant adds $100,000, with an end date of 2010 WPCAMR has applied for a new grant for the 2008 round of GG Applications are available on the GG web site – search under

“quick response” key words The application process is relatively streamlined and

straightforward

Quick Response (continued)Quick Response (continued) Completed applications, with a contractor’s cost estimate

attached, are submitted to the DMO Watershed Manager Watershed Manager and District Mining Manager must approve

project and forward to WPCAMR WPCAMR sends letter to applicant stating whether funding is

approved or not If approved, applicant has contractor complete repairs,

Watershed Manager reviews and approves repairs, WPCAMR then disperses funds to applicant and applies to DEP for reimbursement

Must have signed landowner access and permits, if needed

Types of Projects funded:Types of Projects funded: Damage caused by storm events – damage to ditches, berms,

intake structures and spillways (most frequent cause of funds needed has been damage due to storm events)

Non-storm related berm and pipe damage Sludge removal from compost Replacement of valves Repairs to a stream bank stabilization project after a storm event

(non-AMD project) 11 projects funded so far; costs have ranged from $2,800 to

$55,000

BAMR’s OMR TaskforceBAMR’s OMR Taskforce Established to address OMR needs of BAMR-constructed

passive treatment systems In Cambria office, 2 teams have been established that include

engineers and geologists Have completed 2 evaluations and are currently working on 2

more Most problematic sites are given top priority, but the goal is to

develop an OMR workplan for all 24 systems designed and constructed by the Cambria Office

Harrisburg staff is focusing on BF projects designed there, while Wilkes-Barre staff will be working on projects built by BAMR in their District

Reports will eventually be posted on BAMR’s web site

Draft Set-Aside Position Paper:Plan to Address OMR

Draft Set-Aside Position Paper:Plan to Address OMR

Successful Growing Greener Applicants to handle routine operations

DEP to provide mechanism to fund emergencies and non-routine maintenance; current Quick-Response program provides a template

DEP to develop appropriate application to seek grants for complete or partial system replacement

Funds also will be provided to BAMR for Commonwealth-constructed systems and “orphaned” systems

FundingFunding

DEP has committed $2 million this year to support OMR Set-Aside funding increases under re-authorized SMCRA will

likely be a source of funding for DEP support of OMR The DEP will make funding decisions based on OMR costs for

current systems and what the projected costs will be for future systems; current estimates are that the OMR need is $2 million/year, thereby requiring approx. $46 million to be deposited into an interest-bearing fund, based on current financial scenarios – just for the passive systems currently operating

Set Aside funds used in this manner will not be available to construct treatment facilities, thereby reducing the overall funding available for AMD abatement and treatment projects
