This Regulation establishes Standards , for general and technical design requirements, for use by Department in reviewing Engineering Reports, establishing Reliability Classifications and issuing State Construction Permits or other approval actions as outlined in the Regulation . B. Applicability. This Regulation applies to engineering design and construction of all Wastewater treatment facilities and all Wastewater collection and transmission facilities which require a construction permit or approval from the Department.

5 The Department may approve temporary research and development and other Wastewater treatment projects without requiring an engineering report or construction permit when such activity is considered by the Department to be minor in nature. C. Exclusions. The following exclusions shall apply: 1. Wastewater collection systems approved by permits issued under Regulation 61-56; 2. Replacement of a component (same or similar), as long as there is no change in capacity; 3. Routine maintenance; 4.

6 The construction of buildings; or 5. Service lines as defined in subsection D. General Definitions. All other definitions have the meaning given by the Pollution Control Act. 208 Water Quality Management Plan (208 Plan) means a Statewide and regional plan developed pursuant to Section 208 of the Federal Clean Water Act. 208 Water Quality Management Plan Entity means the government organization responsible for certifying if projects are consistent with 208 Water Quality Management Plans.

7 7Q10 as defined in Regulation 61-68. Actual Flow means a long term average of effluent flow as reported by Discharge Monitoring Reports. Alternative Collection System means a system designed to collect Wastewater from individual sources utilizing solids interceptor tank effluent systems (gravity or pressure), and grinder systems. This definition includes vacuum sewer systems. An exception is where a system such as a grinder pumping system, which serves one building or residence, meets the definition of a service connection ( , force main connecting to a gravity sewer).

8 Alternative Sewer Management Plan means a plan, approved by the Department, that allows entities to authorize individual connections to an alternative sewer collection system (using force main sewers) by an entity participating in the Delegated Review Program. Auxiliary Power means provisions to provide backup electrical and/or mechanical power. BOD means Biochemical Oxygen Demand. 2 | Regulation 61-67 COD means Chemical Oxygen Demand.
