Duration, maintenance and closeout.

A. Duration.

(1) For a project that requires a NYSDEC SPDES permit, the SWPPP approved by the Town of Webster's Public Works Department shall be in effect until the site has been finally stabilized, a notice of termination (N.O.T.) is submitted to the NYSDEC in accordance with the general permit, and a final inspection has been completed by the Town of Webster's Public Works Department.

(2) For projects that do not require a NYSDEC N.O.T., the SWPPP is in effect until a final inspection is conducted and the Town of Webster's Public Works Department has issued the applicant written approval.

B. Maintenance.

(1) The applicant shall at all times properly operate and maintain all stormwater management facilities and erosion and sediment control measures which are installed or used by the applicant to achieve compliance with the conditions of this article. Sediment shall be removed from sediment traps or sediment ponds whenever their design capacity has been reduced by 50%. The land disturbance activity shall not cause an increase in turbidity that will result in substantial visible contrast to natural conditions in surface waters of the State of New York.

(2) At the end of the construction season when soil disturbance activities will be finalized or suspended until the following spring, it may be desirable to reduce the frequency of the required weekly site inspections to monthly inspections. In order to reduce inspection frequencies, the applicant must complete stabilization activities before proper installation is precluded by snow cover or frozen ground. If vegetation is used as a stabilization method, seeding, planting, and/or sodding must be scheduled to avoid fall frosts and to allow for proper germination/establishment. Installations and maintenance must be done according to the New York State Standards and Specifications for Erosion and Sediment Control.

C. Closeout. The applicant must satisfy the following project closeout requirements:

(1) Reestablish grade of all permanent stormwater facilities;

(2) Inspect grading of all drainage structures and provide elevation as-builts to the Town of Webster's Public Works Department;

(3) Establish perennial vegetative cover to a density of 80% over 100% of the site;

(4) Removal of all debris and temporary erosion and sediment control practices;

(5) Provide a written certification by a New York State licensed/certified professional that the site has undergone final stabilization (as defined in Section II) and that all temporary erosion and sediment controls not needed for long-term erosion control have been removed.

(6) Complete any other measure deemed appropriate and necessary by the Town of Webster's Public Works Department to stabilize the project site.
