New State Initiatives 



Guidance) in all subdivisions having impervious area (including roads, driveways, and 

 sidewalks) in excess of 20 percent of the aggregate site area. 



**In critical areas (water supply watersheds, coastal areas, water supply 

 well recharge areas) require that sedimentation basins and infiltration 

 devices be installed (as indicated to be appropriate by Committee 

 Stormwater Guidance) in all subdivisions having impervious area 

 (including roads, driveways, and sidewalks) in excess of 10 percent of the 

 aggregate site area. 



**Develop detailed standards and specifications for off-site detention and 

 retention structures, providing for limitation on contributing drainage area, 

 management of deicing sand, control of runoff, settling to provide 

 attainment of water quality standards, storm flow management, etc. 



***Require that discharges to receiving waters meet applicable water 

 quality criteria, via specified treatment methods if applicable. 



♦♦Require that stormwater management facilities receiving runoff from areas which are a 

 potential source of oil and grease contamination in concentrations exceeding applicable 

 water quality standards include as components baffles, skimmers, grease and oil traps, and 

 other facilities sufficient to ensure proper treatment (See also maintenance provisions 

 below.) 



Construction and Maintenance 



♦♦Work with towns to ensure that local building officials and/or Environmental Officers 

 verify recordation of notice of permit and notice of completion of permit in the land 

 evidence records of the municipality in question as per (Zhapter 13 of Title 34 of RIGL. 



***Require that issuance of occupancy permits be contingent on compliance 

 with the permanent stormwater runoff management measures specified in 

 the applicant's permit. 



♦♦Require that no runoff may enter the project construction drainage area until adequate 

 temporary nmoff and erosion controls have been installed. 



♦♦Require that no runoff be allowed to enter infiltration systems until the fiill contributing 

 drainage area has received final stabilization. 



♦♦Specify procedures for maintenance of baffles, skimmers, grease and oil traps, and other 

 facilities receiving runoff from areas which are a potential source of oil and grease 

 contamination. 



♦♦♦Develop permit conditions which place full responsibility for 

 maintenance of facilities on the contractor until the buyer assumes 

 ownership, and then transfer responsibility to the owner or to the town, depending upon 

 the type of facility at issue and the maintenance required. (Experience in other states has 

 shown that for certain types of facilities, regular town maintenance under a utility or permit 

 fee schedule is much more effective than owner maintenance.)
