the Biosolids Program see:
Permit Fee Program Report


Facilities that work with domestic sewage and biosolids are required to pay a fee to support the state biosolids program. In general, the bigger the waste water treatment facility, and the larger the number of residences that contribute to the facility, the larger the fee. Beneficial use facilities, that only land apply biosolids received from other facilities, pay a reduced fee to avoid charging a fee twice for the same biosolids.

Fees vary, depending upon size and type of facility. For the 2018 fiscal year there is a minimum fee of $956.09 per facility. In addition, there is a one-time fee of $2868.28 for review of new facilities.
