Corpus Christi Enforces Construction Site Rules and Stage 3 Water Restrictions Under Ozone Standards

Corpus Christi maintains its Attainment/Unclassifiable designation for the 2015 8-hour ozone standard of 0.070 ppm under federal EPA regulations across Nueces and San Patricio Counties while the Texas Commission on Environmental Quality applies stationary source rules and city ordinances govern construction and water use.

Stationary Source Rules and Ozone Standards

The Texas Commission on Environmental Quality enforces stationary source rules that limit nitrogen oxides and volatile organic compounds from utility electric generation, water heaters and degreasing processes. These measures support the area's ozone designation and apply to operations that residents rely on for electricity and local services.

Construction Ordinances and Water Restrictions

City ordinances require sites disturbing one acre or more to prepare an NPDES or TPDES storm water pollution prevention plan, while sites disturbing 0.25 to one acre must implement a pollution control plan. Responsible parties inspect measures every 14 days or on a seven-day alternative schedule and within 24 hours after rainfall of 0.5 inches or more, then keep records available for city review. The City of Corpus Christi operates under Stage 3 Water Restrictions because Choke Canyon Reservoir stands at 8.1 percent and Lake Corpus Christi at 33.8 percent as of July 14, 2026.

These requirements affect daily operations for builders, property owners and households by setting inspection intervals and water-use limits that shape project timelines and household routines. Records must be maintained for city inspection, and conservation mandates apply to all users served by the affected reservoirs.

Enforcement continues through existing city and state mechanisms without a stated end date in the current records. The combination of ozone-related limits, storm-water plans and reservoir-driven restrictions remains in place for the designated counties.
