The department offers a review and approval process for municipalities with standard sewer specifications and details. Municipalities that receive department approval will not be required to submit a copy of their specifications and details with a sewer extension construction permit application. You may view approved and currently under review municipalities.
Sewer Extension Authority Supervised Program
According to 10 CSR 20-6.010(6)(A), the department may grant approval of an entity’s sewer extension authority supervised program when the facility has at least one existing treatment plant equal to or greater than 1 million gallons per day (1MGD). Entities with a department-approved program are exempt from construction permit requirements for collection systems. Department approval may be granted for a period of five years in the applicant’s operating permit. At the time of the operating permit renewal, the sewer extension authority supervised program must submit a request for reauthorization and the department will reevaluate the authority..
As part of the review, the department verifies that the entity has sufficient engineering review capabilities, has defined procedures for review, construction, and inspection of projects done by others and those projects done by the entity, how plans are maintained permanently, and that the entity’s standard plans and specifications meet the minimum requirements in 10 CSR 20-8, specifically
Approved sewer extension authority supervised program entities are responsible to permit, inspect and accept sewer extensions constructed within their municipal boundaries and ultimately discharging to a wastewater treatment facility for which they own and act as continuing authority. With an approved program, the entity may have additional requirements in their state operating permit, such as an annual summary report on the projects undertaken during the previous calendar year.
Entities applying for funding under 10 CSR 20-4, “Grants and Loans” will be required to comply with those requirements in addition to their approved sewer extension authority supervised program.
New sewer extension authority program requests must meet the requirements of 10 CSR 20-6.010(6)(B). Municipalities wishing to apply for this program should contact the department's Water Protection Program, Engineering section, at 573-751-1300 or DNR.WPPEngineerSection@dnr.mo.gov.
