N.Y. Comp. Codes R. & Regs. tit. 10, § 128-3.15 – Snow disposal and storage and use of winter highway maintenance materials.

(a) Whenever feasible removed snow shall not be disposed of directly into a watercourse, wetland, reservoir, reservoir stem or controlled lake. However, this subdivision shall not be construed to require an owner or operator to transport the removed snow in a vehicle for offsite disposal.

(c) Commercial, industrial, governmental, or institutional entities shall be restricted to the use of the substances defined in these rules and regulations as winter highway maintenance materials and to the use of the minimum amount needed of such substances in order to protect the public safety. In determining the minimum amount needed for public safety, such entities should consider best management practices developed by the New York State Department of Transportation.

(d)
(e) All commercial, industrial, governmental, or institutional entities that store winter highway maintenance materials in quantities and composition not otherwise subject to paragraph (d)(1) of this section, shall store such materials in a manner that minimizes runoff into any watercourse, wetland, reservoir, reservoir stem, or controlled lake. Runoff may be controlled by use of control measures such as berms and covers.
