Why Operation and Maintenance?

““An ounce of prevention is worth a pound An ounce of prevention is worth a pound of cure.” of cure.” -- Ben FranklinBen FranklinSystems that are not maintained are Systems that are not maintained are destined to fail!!destined to fail!!Failed systems can have significant Failed systems can have significant environmental consequences. environmental consequences.

What Does O, M & R Cost?

Calculating O, M & R Costs

Calculation of factorCalculation of factor: [(actual total O,M&R : [(actual total O,M&R costs)/(life of system)/(construction cost)] X 100costs)/(life of system)/(construction cost)] X 100Calculated an Average O, M & R Factor of 4%Calculated an Average O, M & R Factor of 4%Use of factor:Use of factor: Construction Cost X (O,M&R Construction Cost X (O,M&R factor) = average annual O,M&R for projectfactor) = average annual O,M&R for projectExample:Example: $100,000 project with 4% factor will $100,000 project with 4% factor will cost an average $4,000 per year for O,M&Rcost an average $4,000 per year for O,M&R

How Can Costs Be Reduced?

Sponsor who takes on projected O & M activities Sponsor who takes on projected O & M activities would lessen the O, M & R costs by 20%would lessen the O, M & R costs by 20%--60%60%

Examples:Examples:Sponsor handles routine operation and Sponsor handles routine operation and maintenance (monitoring, sampling, etc.)maintenance (monitoring, sampling, etc.)Major maintenance and replacement costs Major maintenance and replacement costs are based on government bid projects; are based on government bid projects; sponsors who are creative with local sponsors who are creative with local resources may decrease these costsresources may decrease these costs

Revised 11/5/03 Recommendations:• Request that the Legislature establish a non-lapsing O, M & R fund within the

Growing Greener program, establish the fund and initiate deposits to the fund from Growing Greener or other sources;

• Establish an O, M & R quick response contract and procedures for accessing the contract;

• Encourage EPCAMR and WPCAMR to submit Growing Greener grant applications to disburse funds to watershed groups to cover lab analyses costs;

• Provide staff assistance to OSM in developing a web-based GIS database for all AMD treatment projects;

• Continue to provide support for watershed restoration technology transfer conferences.
