(A) A construction permit is valid for a period of six months.
(B) A storage permit is issued for a term of two years. Every application for the renewal of a storage permit shall be made no later than 30 days before expiration of the permit and shall be accompanied by payment of the appropriate renewal fee as established by the city. However, if an underground storage facility or tank system or any part thereof is substantially modified or repaired, the owner and/or operator of the facility or system must renew the storage permit upon completion of the modification or repairs. The existing permit shall remain effective until the city makes a final decision either to grant or deny the pending application for renewal. The city shall notify the permit holder of the expiration date no later than 90 days before the permit expires. No renewal shall be granted unless the city finds that the record of the permit holder's compliance with the provisions of this chapter and with the relevant rules and regulations of the Texas Water Commission and other state, federal and local agencies warrants renewal, that the physical condition of the facility, tank system and all parts thereof meet the minimum standards imposed by this chapter, the Water Commission, and other state, federal and local agencies.
