How are inspections scheduled?
Obtain the OSSF permitting packet from the Environmental Inspection Service, submit the application, site evaluation and required design/planning materials, and call 903-572-6641 to coordinate authorization to construct and the installation inspection before covering or operating the system. The same office approves subdivision OSSF and floodplain information before a plat goes to Commissioners Court. Subdivision applicants must separately coordinate with the County Clerk at 903-577-6796.
Which codes and exemptions should I review?
Titus County Environmental Inspection Service is the county's TCEQ-authorized OSSF permitting authority and designated representative and also reviews floodplain requirements for unincorporated development. OSSF work must comply with the county's TCEQ-approved local order, Texas Health and Safety Code Chapter 366, and 30 TAC Chapter 285. County subdivision rules require one acre of usable property for new single-family OSSF lots, whether or not served by public water, and regulate rural subdivision roads and drainage. The county publishes no adopted general countywide IRC, IBC, electrical, plumbing, mechanical, or fire-code edition; incorporated municipalities may impose separate building requirements. Titus County states that work on any portion of an existing conventional system's lateral lines requires a new permit. Repairs to solid lines, tank lids, broken chlorinators, sprinkler heads, electrical components, and pumps do not require a new permit. An owner may install the OSSF personally, but anyone hired for OSSF work must hold the appropriate license, except a licensed electrician hired for wiring. Existing small lots created before January 1, 1988 may be approved if state separation distances, site evaluation, and all other local-order requirements are met. No county exemption list is published for ordinary cosmetic or structural building work outside floodplain, subdivision, or septic regulation.
