Dairy Discharge Permits

Revisions to 20.6.6 NMAC (Dairy Rule)

NMED is happy to announce that the New Mexico Water Quality Control Commission (WQCC) recently adopted amendments to the Dairy Rule (20.6.6 NMAC). The effective date of the amended Dairy Rule is August 1, 2015.

The amended rule can be found at the above link for 20.6.6 NMAC.

During this transition period, it is important that dairies consult with the Ground Water Quality Bureau (GWQB) on permitting matters. The GWQB recognizes that cooperation between facilities and NMED can result in a better experience throughout the permitting process.

Since the amendments change several requirements under the Dairy Rule, you may wish to review your discharge permit application, draft discharge permit, or final discharge permit accordingly. If you believe a change in your permit application or permit is required, the following section of the Dairy Rule addresses the permit issuance timelines for New Mexico dairies:
