2. Status of Phase 1 and Phase 2 n Phase 1 n Phase 2 n Phase 1 vs. Phase 2 n Municipality’s Role n Department of Environmental Protection’s Role

3. COVERAGE n SWMP will cover: –All of Department’s highways, roadways and railways located within urbanized areas –All interstates regardless of location n 3732 miles of state maintained highways and roads (18% of total)

4. COVERAGE continued n State covers 5554 square miles, 161 square miles of inland water, and 5385 square miles of coastal water under n 169 municipalities - regulated by the Department of Environmental Protection n Old New England state - long history, little record of storm drainage

5. Strategy to Implement n Preparation of SWPP Plan - By Consultant n Minimum Control Measures - Department defines appropriate BMP’s, designates a person(s) and job title responsible for each BMP, defines a timeframe for implementation for each BMP, defines measurable goals for each BMP. - Prepared and implemented by consultant, Department, contractors and the public n Cost to Prepare and Implement Program

6. Cost to Implement Program n Preparation of Stormwater Management Plan - $450,000.00 n Preparation of Mapping - $1,800,000.00 n Update Mapping Annually - $450,000.00 n Annual Maintenance and Design Costs - $9,000,000.00 - $10,000,000.00

12. Design and Maintenance Issues n Sediment basins in tidal zones n Design 50% complete before drainage design started n Best available technologies - 0.1% used because numbers are not available n Maintenance of systems not funded by feds n Reduction of sediment on roads equals more salt, less sand - more complaints of contaminated wells

13. Design and Maintenance Issues continued n Coordination between Design, Maintenance Offices n Staffing n Time Frame n Record Keeping n Consistency with Municipalities
