N.Y. Canal Law § 79
Any person owning or leasing, in whole or in part, any floating elevator used for loading grain, coal, sand, or other material, shall, upon application to and in the discretion of the corporation, be assigned a place for and permitted to keep said floating elevator in the waters of the canal system of this state, at such point as may be most convenient for and for such period of time as may be necessary for the transaction of the business of loading or unloading grain, coal, sand, or other material, shipped or to be shipped on the canals; provided, however, that such floating elevator shall cause no obstruction to the free and uninterrupted use of the canal system by floats navigating thereon. While such elevators are in operation, they shall be equipped with such device or devices as the corporation may determine to prevent the material being loaded or unloaded from such float, from falling into such waters.
