Current through Register Vol. 46, No. 28, July 10, 2024
(a) Pursuant to
					 Environmental Conservation Law, section 43-0112(2) the commission shall prepare
					 a study of the feasibility of reducing the impacts of stormwater runoff in
					 areas where development has already occurred. The recommendations of such study
					 shall be incorporated into stormwater management plans and stormwater
					 regulatory programs. Municipalities nevertheless should identify, early in the
					 planning process, geographic areas and land-based activities requiring
					 attention to alleviate adverse stormwater related impacts upon water quality
					 and erosion. Municipalities are also encouraged to begin to consider policies
					 and methods to address such impacts prior to completion of the study.
(b) The plan may include in relation to such
					 geographic areas and land-based activities:
(1) a description and location of major
					 stormwater outfall points;
(2) an
					 analysis of existing data on flows and pollutants discharged from major
					 stormwater outfalls and an evaluation of the need to gather additional data in
					 order to:
(i) establish baseline levels of
					 elements and compounds being discharged at major stormwater out falls;
					 and
(ii) rank major stormwater
					 outfalls in order of the amount, levels and volume of stormwater and pollutant
					 loads being discharged;
(3) specific objectives which can reasonably
					 be expected to be undertaken by State and local government to reduce or prevent
					 any increase in stormwater runoff and stormwater pollution from new development
					 or redevelopment. In setting specific objectives, the plan shall evaluate the
					 following:
(i) construction of new stormwater
					 management facilities such as siltation traps, catch basins, and/or retention
					 ponds, independently, or as part of any public road project or other
					 development;
(ii) improved
					 maintenance of existing stormwater management facilities;
(iii) targets for reduction in volume of road
					 deicing sand and salts;
(iv)
					 improvements in runoff controls at road sand and salt storage areas;
(v) reduction in the volume of fertilizers
					 and pesticides applied to public and private lands;
(vi) action to improve spring cleanup of road
					 sand and salt including identification of suitable disposal sites;
(vii) alteration of existing stormwater
					 facilities to reduce the volume of stormwater mixed with surface water flows
					 from the undeveloped upland thereby reducing the volume of polluted water to be
					 controlled;
(viii) action to
					 stabilize eroding areas such as road banks, stream crossing sites, sand and
					 gravel mines; and
(ix) action to
					 improve street sweeping, litter and lawn clipping and other housekeeping
					 measures; and
(4) an
					 identification of ponds and wetlands and areas of watercourses now receiving
					 stormwater and an evaluation of their potential to absorb additional stormwater
					 flows and pollutants without undue adverse impacts to the wetland or
					 watercourse.
