MINNESOTA POLLUTION CONTROL AGENCY Vater Quality Division INFORMATION RELATIVE TO REVIEV OF PLANS AND PERMIT APPLICATIONS February 1, 1998 The review of plans and specifications for sevage, industrial vaste or other waste disposal systems and application for permits is made in accordance with the authority conferred by lav (see MS, Section 115.07). Approval of plans and permits is based upon the assumption that the information provided by the applicant is correct and that all necessary legal requirements have been or viII be satisfied. Plans for sevage, industrial~vaste or other waste disposal systems are examined with regard to the design features vhich apply to operation and maintenance of the treatment works or sever system, the degree of treatment to be provided, the effectiveness and reliability. of the system or methods employed, and compliance with applicable standards systems. The bulletin entitled Recommended Standards for Vastevater Facilities, 1991 Edition, and supplements thereto, as veIl as other information are used in examination of the design, operation and maintenance aspects of the proposed system. Sewer plans are recommended for approval on the basis that the system is to collect only domestic sevage and such industrial or other vaste as may have been provided for in the design. Foundation or footing drains to collect ground water and roof drains or other surface vater conduits should not be connected to the sanitary sewer system. Adequate field supervision and inspection by a qualified representative of the owner should be provided at all times during construction to assure that the project is constructed in compliance vith the approved plans and specifications. The Agency assumes no responsibility for the integrity of structures or physical features, or for the reliability, durability or efficiency of specific items of propriety equipment or material. All applicable federal, state and local laws, regulations or ordinances must be followed in the design, location. and construction of proposed sewer systems or treatment works. The Agency reserves the right to vithdrav its approval of plans if construction is not undertaken within a reasonable period after issuance of the permit.
