(9) 
Maintenance schedule to ensure continuous and effective operation of the erosion and sediment control practices. The maintenance inspection schedule shall be in accordance with the requirements in the most current version of the technical standard, New York State Standards and Specifications for Erosion and Sediment Control.
(10) 
Description and location of any stormwater discharges associated with industrial activity other than construction at the site, including, but not limited to, stormwater discharges from asphalt plants and concrete plants located on the construction site.
(11) 
Description of the pollution prevention measures that will be used to control litter, construction chemicals and construction debris from becoming a pollutant source in stormwater runoff.
(12) 
Description of construction and waste materials expected to be stored on site with updates as appropriate, and a description of controls to reduce pollutants from these materials, including storage practices to minimize exposure of the materials to stormwater, and spill prevention and response.
(13) 
Identification of any elements of the design that are not in conformance with the requirements in the most current version of the technical standard, New York State Standards and Specifications for Erosion and Sediment Control. Include the reason for the deviation or alternative design and provide information which demonstrates that the deviation or alternative design is equivalent to the technical standards.
(14) 
Stormwater quantity and quality controls, at the discretion of the SMO and/or the Town Engineer, may be required.
D. 
Postconstruction stormwater management practice component.
(1) 
All construction projects identified as needing postconstruction stormwater management practices pursuant to the SPDES General Permit for Construction Activities shall prepare a SWPPP that includes practices designed in conformance with the Design Manual, including green infrastructure practices, in addition to the items listed under § 189-8C above. Where postconstruction stormwater management practices are not designed in conformance with this technical standard, the applicant must demonstrate equivalence to the technical standard.
(2) 
At a minimum, the postconstruction stormwater practice component of the SWPPP shall include the following:
(a) 
Identification of all postconstruction stormwater management practices to be constructed as part of the project.
(b) 
Site map/construction drawing(s) showing the specific location(s) and size(s) of each postconstruction stormwater management practice.
(c) 
Hydrologic and hydraulic analysis for all structural components of the stormwater management control system for the applicable design storms. The analysis shall include tributary area maps with two-foot contours for the predevelopment and postdevelopment conditions.
(d) 
Detailed summary (including calculations) of the sizing criteria that was used to design all postconstruction stormwater management practices. At a minimum, the summary shall address the required design criteria from the applicable chapter of the Design Manual; including the identification of and justification for any deviations from the Design Manual, and identification of any design criteria that are not required based on the design criteria or waiver criteria included in the Design Manual.
(e) 
Identification of any elements of the design that are not in conformance with the Design Manual. Include the reason for the deviation or alternative design and provide information which demonstrates that the deviation or alternative design is equivalent to the technical standards.
(f) 
Comparison of postdevelopment stormwater runoff conditions with predevelopment conditions.
(g) 
Dimensions, material specifications and installation details for each postconstruction stormwater management practice or facility.
(h) 
Site maps must include existing topography with two-foot contours, a proposed grading plan with a limit of disturbance line and the calculated area of disturbance in acres.
(i) 
An operations and maintenance plan that includes inspection and maintenance schedules and actions to ensure continuous and effective operation of each postconstruction stormwater management practice or facility. The plan shall identify the entity that will be responsible for the long-term operation and maintenance of each practice.
E. 
Enhanced phosphorus. All projects that are required to conform to the enhanced phosphorus removal standards, pursuant to the SPDES General Permit for Construction Activities, shall prepare a SWPPP that includes postconstruction stormwater management practices designed in conformance with the enhanced phosphorus removal standards included in the Design Manual. At a minimum, the postconstruction stormwater management practice component of the SWPPP shall include items Subsection D(2)(a) through D(2)(i) above.
The applicant shall assure that all other applicable environmental permits have been or will be acquired for the land development activity prior to the issuance of a Town stormwater permit.
A. 
All certifications required pursuant to the SPDES General Permit for Construction Activities shall be submitted, endorsed and incorporated into the SWPPP.
B. 
Each contractor and subcontractor identified in the SWPPP who will be responsible for installing, constructing, repairing, inspecting and maintaining the erosion and sediment control practices included in the SWPPP and the postconstruction stormwater management practice installation must sign and date a copy of the following contractor certification statement before undertaking any land development activity: "I hereby certify that I understand and agree to comply with the terms and conditions of the SWPPP and agree to implement any corrective actions identified by the qualified inspector during a site inspection. I also understand that the owner or operator must comply with the terms and conditions of the most current version of the New York State Pollutant Discharge Elimination System ("SPDES") General Permit for Stormwater Discharges from Construction Activities and that it is unlawful for any person to cause or contribute to a violation of water quality standards. Furthermore, I understand that certifying false, incorrect or inaccurate information is a violation of the referenced permit and the laws of the State of New York and could subject me to criminal, civil and/or administrative proceedings."
C. 
The certification must include the name and title of the person providing the signature, address and telephone number of the contracting firm; the address (or other identifying description) of the site; and the date the certification is made.
D. 
The certification statement(s) shall become part of the SWPPP for the land development activity.
E. 
A copy of the SWPPP, including the above certification(s), shall be retained at the site of the land development activity during construction from the date of initiation of construction activities to the date of final stabilization.
