Deviation from the mandatory “shall” or “must” requirements will be considered by the department based on the primary purpose of the proposed water works, the local conditions governing their functions and operation. The department will consider specific exceptions upon request by submitting the Public Drinking Water Design Standards Exception Request. In no case shall an exception be approved if granting such poses a proven public health risk. Reasons for a request for exception may include, but are not limited to, the following.
- The proposal provides equivalent or superior proven performance;
- New technology is available; or
- Excessive cost of construction relating to the necessity for upgrading existing infrastructure that is within its design life.
The department will approve or deny an exception based on justification and supporting documentation provided by the applicant and the engineer. Decisions may be subject to past experience, risk-based analysis and the applicant’s prior history of compliance.
Length of Permit
If an exception request is granted, the exception will remain in effect until the department determines it no longer meets the requirements.
