Nutrient removal from existing stormwater BMPs including infiltration basins, detention ponds, and bioretention gardens. The BAT tool (BMP assessment and tracking tool) is being implemented. This task is almost complete. Task 4. Annual stormwater BMPs inspection – evaluate to see if maintenance is required. A brief memorandum will be submitted. Task 5. Dry weather outfall sampling - There are 369 known stormwater outfalls that need to be inspected during dry weather flow. Of those 369 there are 57 outfalls that have been unable to access/locate. N. Cristoforia suggests allowing CEI to use the budget to try to locate these outfalls. Due to input from H. Lemieux -money needs to be spent by this fiscal year. J. Rabbitt motions to approve the budget- Seconded by M. Allison. Task 6. Regulatory mechanism assistance – Phase 1- the first application under the new bylaws is being presented to the planning board.

Stormwater utility feasibility study – Introductory study on stormwater utility and prevention in order to develop stormwater utilities. This is a multi-year phased approach.
