         (x)   Construction of an impervious surface in the East of Hudson Watershed in a Designated Main Street Area.
      (5)   If there is a significant change in design, construction, operation, or maintenance of an activity which is subject to a Stormwater Pollution Prevention Plan pursuant to subdivision (b)(3) which may have a significant effect on the potential for the discharge of pollutants to surface waters and which has not otherwise been addressed in the Stormwater Pollution Prevention Plan, or if the Stormwater Pollution Plan proves to be ineffective in eliminating or significantly minimizing erosion and sedimentation or the discharge of pollutants associated with construction activity, the Stormwater Pollution Prevention Plan must be amended. Such amended stormwater pollution prevention plan shall be submitted to the Department for prior review and approval and shall comply with the requirements of this section.
      (6)   Any approval of a stormwater pollution prevention plan issued by the Department expires and is null and void unless construction is completed within five (5) years of the date of issuance or within any extended period of time approved by the Department upon good cause shown. Following expiration of the approval, the application for the stormwater pollution prevention plan may be resubmitted to the Department for consideration for a new approval.
      (7)   As a condition of approval the Department may require evidence of financial security prior to construction from any owner or operator of a stormwater management system pursuant to a stormwater pollution prevention plan. Such financial security shall consist of a bond, or an equivalent guaranty, to be deposited with the Department, covering the full cost of the construction of such facility and an additional bond or an equivalent guaranty for the payment of labor and material furnished in the course of such construction. Upon completion of construction and payment of labor and materials, such bonds or other guaranties shall be released. Additionally, a bond or equivalent guaranty may be required for the maintenance and operation of the facility for a period of five years post-construction. No bond or guaranty is required where the owner or operator of such a facility is a village, town, county or city.
      (8)   Where portions of an activity that require a stormwater pollution prevention plan pursuant to subdivision (b)(3) constitute redevelopment as defined herein, those portions of such plan shall:
         (i)   be prepared and implemented, to the extent possible, in accordance with the requirements of Part III of the New York State Department of Environmental Conservation SPDES General Permit No. GP-0-15-002 that are applicable to the construction activities identified in Table 2 of Appendix B;
      (9)   Where an activity requiring Department review and approval of a stormwater pollution prevention plan under this section that involves disturbance of less than one (1) acre of total land area, other than construction of a gasoline station or construction, alteration, or modification of a solid waste management facility, and which will not result in hot spot runoff, requires a stormwater pollution prevention plan pursuant to subdivision (b)(3) above, the application must consist of:
         (i)   A plan of the proposed activity, identifying the area of disturbance, the location of any existing or proposed impervious surfaces, and the location of any watercourses, wetlands, reservoirs, reservoir stems or controlled lakes on or adjacent to the property;
         (ii)   A description and depiction of proposed erosion controls sufficient to prevent sedimentation of the receiving watercourse, wetland, reservoir, reservoir stem or controlled lake on or adjacent to the property during construction. Erosion controls typically consist of sediment barriers, such as hay bales and silt fencing, temporary sediment traps and temporary stormwater flow diversions;
         (iii)   A schedule for construction, including grading and site stabilization; and
         (iv)   A description and depiction of proposed permanent stormwater management practices designed to filter, detain, or infiltrate runoff from impervious surfaces, thereby minimizing the post-construction increase in pollutant loading to the receiving watercourse, wetland, reservoir, reservoir stem or controlled lake.
   (c)   Additional Requirements for Stormwater Pollution Prevention Plans.
      (1)   When any activity listed in paragraph (3) of subdivision (b) of this section is proposed to be undertaken in the drainage basin of a terminal reservoir, as identified in the watershed maps in Appendix 18-A, the stormwater pollution prevention plan shall include analysis of coliform runoff, before and after the land disturbance activity.
         (i)   If such proposed activity causes or contributes to the contravention of the coliform standard set forth in 15 RCNY § 18-48(b)(1), the stormwater pollution prevention plan shall not be approved by the Department, unless the measures required by the stormwater pollution prevention plan in conjunction with any other controls to be imposed that limit future land disturbance at the site, including but not limited to property easements, restrictive covenants, zoning laws and development by-laws, will prevent the contribution of additional coliform.
      (2)   Stormwater Conveyance Measures. Stormwater pollution prevention plans prepared pursuant to this section shall provide for the maintenance of natural drainage systems, including perennial and intermittent streams, and the use of swales and drainage ditches in an open condition to the maximum extent practicable. A stormwater pollution prevention plan shall ensure that any closed stormwater conveyance measures are sized appropriately to convey, at a minimum, the 10-year, 24-hour storm flow.
      (3)   Stormwater Treatment Volume. All stormwater pollution prevention plans prepared pursuant to this section shall include measures to capture and treat the greater of the volume of runoff generated by the 1-year, 24-hour storm or the Water Quality Volume (WQv), except that a stormwater management practice may be designed to capture and treat the lesser of those volumes if it is a stormwater infiltration practice or it is a bioretention practice in hydrologic soil group A or B. Stormwater management practices which provide treatment shall be designed to accommodate the quantity of runoff flowing to the stormwater management practice, including runoff from off-site areas.
      (4)   Where a stormwater pollution prevention plan prepared pursuant to this section includes a stormwater infiltration practice, to the maximum extent practicable, no portion of such stormwater infiltration practice shall be located within 100 feet of any portion of the absorption field of a subsurface sewage treatment system.
      (5)   To the maximum extent practicable, an activity requiring a stormwater pollution prevention plan, and the stormwater pollution prevention plan prepared for such activity, shall be designed:
         (i)   To minimize the alteration of the existing drainage areas and to maintain the volumes of flow at design points at pre-construction levels, except as necessary to alleviate downstream flooding problems or other adverse conditions in existence prior to construction, or to divert runoff from off-site and/or undisturbed areas away from areas proposed to be disturbed.
         (ii)   To minimize loss of annual recharge to groundwater by maximizing the use of stormwater infiltration practices where suitable soil conditions exist.
      (6)   If an activity requiring a stormwater pollution prevention plan will result in impervious surfaces covering twenty percent (20%) or more of the drainage area for which a stormwater management practice is designed, the stormwater pollution prevention plan shall provide for stormwater runoff from that drainage area to be treated by two different types of stormwater management practices in series, except that only one stormwater management practice is required if either:
         (i)   the stormwater management practice provided is a stormwater infiltration practice; or
         (ii)   the activity requiring a stormwater pollution prevention plan is in the West of Hudson watershed within a village, hamlet, village extension, or area zoned for commercial or industrial uses or in the East of Hudson watershed within a Designated Main Street Area.
      (7)   For purposes of the design criteria incorporated by reference in New York State Department of Environmental Conservation SPDES General Permit No. GP-0-15-002, "detention time" shall mean the time runoff is detained in a stormwater management practice. It can be computed using either the center of mass method or the plug flow method.
   (d)   Application requirements and procedures.
      (1)   An application for approval of a stormwater pollution prevention plan shall include:
         (i)   The pollution prevention plan; and
         (ii)   The information required in a Notice of Intent under New York State Department of Environmental Conservation SPDES General Permit No. GP-0-15-002.
      (2)   When the Department notifies an applicant that an application for approval of a stormwater pollution prevention plan is complete pursuant to 15 RCNY § 18-23(d)(2) and (3), the Department shall also issue a written notification to the Stormwater Project Review Committee ("Committee") for the Town(s) or Village in which the activity requiring preparation of the stormwater pollution prevention plan is proposed to be located, of the Department's receipt of a complete application.
         (i)   If requested by one or more members of the Committee, the Department shall submit a copy of the complete application to the Committee for its review and shall convene a meeting, in person or by telephone, of the Committee.
         (ii)   The Department shall not be required to meet with or otherwise further consult with a member of the Committee concerning an application where the Committee member declines to review the application or fails to attend a meeting of the Committee convened to consider the application.
      (3)   Upon completion of their review of the application, and upon a majority vote of the Committee members, including the Department's Committee member, who reviewed the application, the Committee may recommend to the Department that an application for approval of a stormwater pollution prevention plan be approved, approved with conditions or disapproved.
         (i)   If the Department's Committee member agrees with the majority recommendation of the Committee, the Department may proceed to issue its determination to the applicant.
         (ii)   If the Department's Committee member disagrees with the majority recommendation of the Committee, the application, together with the written recommendation of the Committee, shall be submitted to the Commissioner of the Department for review and a determination. The Commissioner shall issue a written record of decision setting forth the basis for the determination and responding to any contrary written recommendations submitted by any member of the Committee.
         (iii)   If the Committee fails to make a recommendation to the Department at least fifteen (15) days prior to the date the Department is required to notify an applicant in writing of its determination pursuant to 15 RCNY § 18-23(d)(5), the Department may proceed to issue its determination and the Department shall not be required by these rules and regulations to further consult with or consider the comments of the Committee or any member of the Committee.
      (4)   Failure of any Committee member, other than the Department Committee member, to act in accordance with the procedures or within the time frames set forth in these rules and regulations, shall relieve the Department of any obligation to consult with or consider the comments of the Committee member. Failure of any Committee member, other than the Department Committee member, to act in accordance with the procedures or within the time frames set forth in these rules and regulations, shall not invalidate any determination issued by the Department.
      (5)   A Committee may only make recommendations to the Department and shall have no authority to make decisions on behalf of the Department. For purposes of SEQRA, the Department's determination on an application, not the Committee's recommendation to the Department, shall be considered a final decision.
   (e)   Individual residential stormwater permits.
      (1)   An individual residential stormwater permit is required for:
         (i)   Construction of a new individual residence, not located within a subdivision, and located within the limiting distance of 100 feet of a perennial stream or wetland;
         (ii)   Construction of a new individual residence located within a subdivision approved before October 16, 1995, and not prohibited by paragraph (a)(5)(ii)(b) of this section, and located within the limiting distance of 100 feet of a perennial stream or wetland; and
         (iii)   Construction of an impervious surface for a driveway to serve an individual residence that obtains all discretionary approvals necessary for construction on or after March 1, 2010, located within the limiting distances of 50 feet of an intermittent stream or wetland or within 100 feet of a perennial stream, except that no individual residential stormwater permit is required if the driveway is included in an activity requiring Department approval of a stormwater pollution prevention plan.
      (2)   Application requirements. An application for issuance of an individual residential stormwater permit shall include:
         (i)   A plan of the proposed individual residence and/or driveway;
         (ii)   A plan or map identifying the location of any watercourses, wetlands, reservoirs, reservoir stems or controlled lakes on or adjacent to the property;
         (iii)   A plan showing the approximate area of site disturbance;
         (iv)   A description and depiction of proposed erosion controls sufficient to prevent sedimentation of the receiving watercourse or wetland during construction. Erosion controls typically consist of sediment barriers, such as hay bales and silt fencing, and temporary stormwater diversions;
         (v)   A schedule for construction, including grading and site stabilization; and
         (vi)   A description and depiction of proposed stormwater best management practices designed to filter, detain, or filtrate runoff from the individual residence or driveway, thereby minimizing the post-construction increase in pollutant loading to the receiving perennial stream or wetland.
      (3)   An individual residential stormwater permit issued by the Department shall expire and thereafter be null and void unless construction is completed within two (2) years of the date of issuance of the permit, or within any extended period of time approved by the Department upon good cause shown. Following expiration of the permit, the application for the individual residential stormwater permit may be resubmitted to the Department for consideration for a new permit.

§ 18-40 Miscellaneous Point Sources.
   (a)   Unless otherwise permitted by the rules and regulations, a discharge, or storage which is reasonably likely to lead to a discharge into the environment (including into groundwater), from industrial facilities, including vehicle washing facilities, and which is reasonably likely to cause degradation of surface water quality or of the water supply, is prohibited. It shall be an affirmative defense under this subsection that such discharge, or storage likely to lead to a discharge, is either permitted or not prohibited under federal law, and is either permitted or not prohibited under state law.
   (b)   Any new point source, excluding point sources otherwise regulated pursuant to these rules and regulations, is prohibited from discharging into a reservoir or controlled lake, reservoir stem, or wetland.
§ 18-41 Solid Waste.
   (a)   Siting or horizontal expansion of a junkyard or a municipal solid waste landfill, within the limiting distance of 250 feet of a watercourse or wetland, or the siting or horizontal expansion of a junkyard or a solid waste management facility within the limiting distance of 1,000 feet of a reservoir, reservoir stem or controlled lake is prohibited except for:
      (1)   Recyclable handling and recovery facilities that handle non-putrescible solid waste, such as newspapers, magazines, corrugated boxes, glass, cans and plastic, but not non-putrescible solid waste such as batteries, car batteries, and waste oil;
      (2)   Composting facilities for individual households for personal use; or
      (3)   Expansion of the existing permitted municipal solid waste landfill located within Delaware County.
   (b)   Discharge of solid waste directly into any watercourse, wetland, reservoir, reservoir stem or controlled lake is prohibited. For purposes of this subdivision, solid waste includes materials that are otherwise exempt from compliance with 6 NYCRR Part 360, as described in 6 NYCRR § 360.2(a)(3), unless those materials are irrigation return flows, materials that are used for artificial reefs in compliance with applicable State requirements, or authorized to be discharged to waters of the state pursuant to a valid permit issued by the New York State Department of Environmental Conservation pursuant to Environmental Conservation Law article 15, 17, 24, 25, or 34 or a water quality certification issued under Section 401 of the Federal Water Pollution Control Act. This subdivision shall not apply to discharge of treated leachate in accordance with the requirements of these rules and regulations and a valid SPDES permit.
   (c)   Only construction and demolition debris that is recognizable uncontaminated concrete, asphalt pavement, brick, soil, stone, trees or stumps, wood chips, or yard waste may be used as fill in the watershed.
   (d)   All new solid waste management facilities, or altered or modified existing solid waste management facilities within the limiting distance of 300 feet of a watercourse or wetland, or within the limiting distance of 500 feet of a reservoir, reservoir stem, or controlled lake, are required to submit stormwater pollution prevention plans to the Department for review and approval, in accordance with 15 RCNY § 18-39(b)(3)(v).
