• Jurisdiction: New Hampshire
• Title L: WATER MANAGEMENT AND PROTECTION
• Ch. 485-A: WATER POLLUTION AND WASTE DISPOSAL
• Subdivision: Sewage Disposal Systems

Text

I. Prior to expanding any structure or any change in use, which would increase the load on a sewage disposal system, the owner of such structure shall submit an application for approval of the sewage disposal system to the department. Application for approval shall include one of the following:
(a) Evidence that the existing sewage disposal system meets the requirements of the department for the intended usage or the town's minimum standards for use or occupancy prescribed under RSA 48-A:11, whichever is more stringent.
(b) The design for a new system which meets the requirements of the department for the intended use or the town's minimum standards for use or occupancy, whichever is more stringent.
II. The fee for application under this section shall not exceed fees charged for new design applications.
II-a. (a) No construction or operational approval shall be required from the department prior to expanding, relocating, or replacing any structure that does not increase the load on a sewage disposal system, as long as all of the following conditions are met:
(1)(A) The lot is served by a sewage disposal system that received construction and operational approval from the department within 20 years of the date of the issuance of a building permit for the proposed expansion, relocation, or replacement; or
(B) The lot is 5 acres or more in size and is served by a sewage disposal system that received construction and operational approval from the department; or
(C) The lot is served by a sewage disposal system with an off lot effluent disposal area that received construction and operational approval from the department.
(2) If the property is nonresidential, no waivers were granted in the construction or operational approval of any requirements for total wastewater lot loading, depth to groundwater, or horizontal distances to surface water, water supply systems, or very poorly drained soils.
(3) When applicable, the proposed expansion, relocation, or replacement complies with the requirements of the shoreland water quality protection act, RSA 483-B.
(b) An owner of a project that requires department approval to proceed because neither of the conditions of subparagraphs (a)(1)(A) or (B) are met, may either submit for approval a design for a new sewage disposal system or apply for a permit by rule for in-kind replacement under RSA 485-A:33, IV. Under either approach, once approval for the sewage disposal system is received from the department, work may commence on expanding, relocating, or replacing the structure. Construction of the sewage disposal system is not required to satisfy the requirements of this subparagraph.
III. The commissioner shall adopt rules under RSA 541-A requiring a person to comply with the provisions of paragraph I before taking any action which would increase the load on a sewage disposal system.
