New State Initiatives 



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

 well recharge areas) require that sedimentation basins and infiltration 

 devices (where appropriate) be installed on all sites as necessary to prevent 

 disturbed areas from contributing to sediment erosion. 



♦♦Require that sediment laden waters from the site be treated in an appropriate facility 

 designed to remove particles of 100 microns or greater for one year design stonns or for 

 the iughest dewatering pumping rate, whichever is most critical. 



Construction and Maintenance 



♦♦♦Work with towns to ensure that local building officials, environmental 

 officers, or Conservation District Personnel inspect sediment/erosion 

 control installations to ensure compliance with specifications and adequacy 

 of function as outlined below, and in the related sub-section on enforcement. Require 

 that issuance of occupancy permits be contingent on compliance with the pennanent 

 sediment and erosion control measures specified in the applicant's permit. 



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

 temporary mnoff and erosion controls have been installed- 



♦♦♦Develop permit conditions which place full responsibility for maintenance of facilities 

 on the contractor. 



♦♦Ensure that project scheduling, and seeding and mulching schedules and practices 

 outiined in the plan are adhered to. 



♦♦♦Provide detailed maintenance requirements which ensure that practices/controls operate 

 in conformance with applicable construction and performance standards. 



♦♦Given that the timing and severity of erosion and sedimentation impacts will depend on 

 project duration, seasonality and climatic factors, provide for inspection of facilities at 

 appropriate junctures during the process of construction of all primary control facilities, or, 

 at a minimum, at least twice during project construction. Provide for inspection to ensure 

 that the developer has adequately provided for the preventive maintenance of installed 

 structures, particularly following storm events. 



♦♦Provide for revision of permit specifications to require structural modifications if 

 changed hydrologic or other circumstances dictate that the facility must be upgraded in 

 order to meet water quality protection needs. 



B. Specific Stormwater Management Requirements 



Applicability 



♦♦♦Specify that all: subdivisions; projects involving placement or repair of 

 roads; utilities; projects involving placement or repair of underground pipe 

 of specified dimensions; feed or holding lots which provide for a specified 

 number of animals; storage or distribution systems for petroleum products 

 or chemicals; storage, distribution or treatment systems for liquid waste; 

 solid waste storage, disposal, or incineration sites; sludge or sludge
