Contributing Zone Plans (CZP)
According to the Comal County Order Adopting Rules for On-Site Sewage Facilities, a Contributing Zone Plan, as defined by TAC Chapter 213, shall be approved by the appropriate TCEQ regional office before an authorization to construct may be issued for an OSSF by Comal County.
Due to this rule, Comal County asked the TCEQ for all CZP approval letters for developments within Comal County. The Comal County Engineer’s Office has made available electronic versions of these approval letters on the CCEO website. In addition, copies of the applications are available at the Comal County Engineer’s Office.
