Water Quality Standards

Impervious Cover Limit
No citywide impervious cover cap; drainage systems must accommodate design storm flows
On-Site Treatment Required
No
Detention Required
Yes
Detention Standard
Detention required to limit post-development peak flows to pre-development levels for 2-, 10-, and 100-year storms per City of Midland Drainage Design Standards; flat arid terrain with ephemeral draws requires careful storm routing
Turbidity Standard
No numeric NTU limit; discharges must comply with TCEQ TXR150000; Permian Basin caliche soils produce significant sediment loads when disturbed

Local SWPPP / Drainage Plan

Local Plan Required
Yes
Plan Name
SWPPP per TCEQ TXR150000; drainage report required for local permit
PE Stamp Required
Yes
Drainage study prepared by a Texas PE required for permits. Permian Basin oil and gas development creates significant construction activity; industrial and commercial sites must address both water and wind erosion. Caliche soils are highly erodible when wet and must be stabilized promptly. Oilfield chemical and produced water spill prevention must be addressed in SWPPP for projects near oil and gas infrastructure.

Local Inspection Requirements

Requirements
City of Midland Engineering Department inspects grading permits at rough grading and final stabilization. Summer thunderstorm season (July–September) can produce intense localized flooding.
Inspector Qualification
No city-specific certification required beyond TCEQ SWPPP requirements

Special Overlay Zones

Ephemeral Drainage Channels / Permian Basin Draws
Trigger: Development crossing or adjacent to ephemeral drainage channels, playas, or natural draws
Restriction: Drainage channels and playas must not be filled without compensatory storage; culvert crossings must be sized for 100-year flow; erosion protection of channel banks required
FEMA Special Flood Hazard Area (SFHA)
Trigger: Development within FEMA-mapped 100-year floodplain
Restriction: Floodplain development permit required from City of Midland Floodplain Administrator; no net fill without compensatory storage

Jurisdiction Notes

Midland is the hub of the Permian Basin, one of the world's most productive oil-producing regions. The high volume of oil and gas construction activity creates significant stormwater compliance responsibilities. The arid climate (averaging ~14 in/year rainfall) means storms are infrequent but can be intense. Caliche soils typical of the Permian Basin are easily eroded when disturbed by construction equipment. Many construction sites in the basin involve proximity to pipelines, wellheads, and processing facilities, which requires additional spill prevention planning in the SWPPP.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
