Texas Natural Resource Conservation Commission Austin Texas Interoffice From: Lawrence E. Pewitt, P.E., Director, Permits Division To: Permit Engineers Date: December 21, 1987 Subject: Permit Renewals - Claiming of a Standard Exemption During the review of an application for permit renewal, a company may elect to not continue the permit but claim a standard exemption. This will be allowed; however, we will need to indicate to the permit holder that if this choice is made, the possibility of amending a standard exemption is not available. We should not encourage a permit holder to claim a standard exemption because of this limitation. cc: Mr. James C. Myers, P.E., Director, Enforcement Program Mr. Steve N.
