Comment on Ammonia Nitrogen Criteria Guidance
Missouri Ag Connection - 12/02/2019
The Missouri Department of Natural Resources, Water Protection Program is seeking public comments on its 2019 Total Ammonia Nitrogen Criteria Implementation Guidance (2019 guidance). The 2019 guidance will replace the 2007 Total Nitrogen Criteria
Implementation Guidance for establishing ammonia limits in Missouri State Operating Permits.
The 2019 guidance establishes a new method for developing protective ammonia limits. In addition to having more consistent values, the new derivation method is more efficient resulting in less time conducting calculations for limits. The proposed 2019 guidance
is located at dnr.mo.gov/env/wpp/wpcp-pn.htm.
Persons wishing to comment on the proposed 2019 guidance are invited to submit them in writing to: Department of Natural Resources, Water Protection Program, P.O. Box 176, Jefferson City, MO 65102-0176, Attn: NPDES Operating Permits/2019
guidance Comments. Email comments will be accepted at the following address: email@example.com.
The public comments for the 2019 guidance will end on Dec. 27. The Department will consider all written comments including emails, faxes, and letters in the formulation of the final determination of the 2019 guidance.
