Universal Citation: 6 NY Comp Codes Rules and Regs § 750-2.11

Current through Register Vol. 46, No. 39, September 25, 2024

(a) This section applies to any and all disposal systems permanently removed from use or operation at SPDES permitted facilities or at facilities for which a SPDES permit has been revoked or an application for renewal denied, unless a judicial or administrative stay is in effect. The intent of this section is to protect public safety and health and to assure that no contamination of ground or surface water will occur as a result of removing such systems from service either through the act of closure or through continuing the discharge of pollutants into or through equipment; or through leaking, leaching, or discharge of pollutants from wastewater or residuals remaining in disposal systems which has been removed from use but remains on site.

(b) The closure of a disposal system means either the termination of the source of wastewater or storm water, or the permitted conveyance of wastewater or storm water to an alternate location (such as a regional facility) in such a manner that no further treatment storage or conveyance of wastewater or storm water is performed by the system.

(1) On or before 60 calendar days prior to taking the system out of service a permittee shall:

(i) submit to the regional water engineer the following information concerning closure activities:

(a) the date the system will cease operation;

(b) the date the influent and effluent pipes will be sealed;

(c) plans (signed and sealed by a New York State licensed professional engineer) for final disposition of the physical facilities, including all treatment units, outfall line, and all mechanical and electrical equipment and piping;

(d) plans (signed and sealed by a New York State licensed professional engineer) for elimination of all equipment and/or conditions that could possibly pose a safety hazard, either during or after shut-down of operations;

(e) verification that there are no lines in the collection system which are cross connected (receiving both sanitary and storm water) or which do not contain adequate conveyance capacity;

(f) the name of the licensed individual responsible for the maintenance and operation of the wastewater pumping station and/or disposal system systems that are still to be maintained; and

(ii) notify the regional water engineer, in writing, concerning any deactivated lagoons or other actual or potential discharges to ground water which may exist at the site.

(2) Proper management and/or removal of all residual materials (collected grit and screenings, scums, sand bed material, and dried or liquid sludges), as well as filter media, and all other solids from the treatment process that may remain in the abandoned treatment works is required.

(i) The permittee shall submit to the regional water engineer proof of ownership of or contractual arrangement with an operation or operations permitted to manage all such waste materials. A contract with a hauler will only be accepted as proof of proper waste management if documentation of management at an approved site or sites is included. In addition, all necessary State or Federal permits/approvals must accompany the submission.

(ii) All residual material shall be removed within 180 calendar days after the system is taken out of service. Proof of proper residuals management shall be submitted to the regional water engineer within 30 calendar days after their removal. The dates of removal and quantities removed shall be specified.

(d) Upon satisfaction of closure requirements specified in subdivision (c) of this section, the regional water engineer shall be contacted, in writing, to schedule a final site inspection of any disposal system which had a SPDES discharge permit to verify that influent and effluent pipes have been sealed and that all solid and residual materials related to the treatment process have been removed.
