- SWPPP is not required.
Between 1 and 5 acres:
- TCEQ CGP coverage is required.
- SWPPP must be prepared and implemented.
- Site notice must be posted with a copy being sent to stormwater@wcid17.org.
Over 5 acres:
- TCEQ CGP coverage is required.
- SWPPP must be prepared and implemented.
- Site notice must be posted with a copy being sent to stormwater@wcid17.org.
- NOI should be submitted to TCEQ.

WCID No. 17 Expectations
In addition to following all applicable federal and state requirements, construction sites within WCID No. 17 jurisdiction must also follow the following set of WCID No. 17 requirements:
Stormwater Inspector Requirement
Contractors must hire and maintain their own Qualified Stormwater Inspector to:
- Perform regular stormwater inspections in accordance with the TPDES Construction General Permit (CGP) and the project’s SWPPP.
- Ensure all stormwater control measures (BMPs) are properly implemented, maintained, and modified as necessary.
- Document all inspections and corrective actions in compliance with CGP requirements.
Inspection Report Submittal
- All stormwater inspection reports completed by the contractor’s Qualified Inspector must be submitted to WCID No. 17’s MS4 program.
- Submit reports by email to stormwater@wcid17.org.
- Reports should be submitted no later than 48 hours after each inspection is conducted.
Site Access and Oversight by WCID No. 17
- WCID No. 17’s Stormwater Inspector will conduct periodic oversight inspections of active construction sites to verify compliance.
- Oversight inspections are not scheduled and may occur at any time, including after rain events or in response to a complaint or observed issue.
- The WCID Inspector’s role is to verify that stormwater control measures are in place and functioning as intended – not to replace the contractor’s inspection responsibilities.
Site Contact Requirement
- Contractors must provide the name and contact information of the project’s Stormwater Inspector and the site superintendent or other responsible personnel to WCID No. 17 before construction begins.
- Updated contact information must be provided if there are staffing changes.
Prompt Corrective Actions
- If deficiencies are identified during WCID No. 17 oversight inspections, prompt corrective actions must be taken by the contractor.
- Contractors are expected to address deficiencies within 24 hours, or as otherwise specified based on the severity of the issue.
Communication and Collaboration
- WCID No. 17 encourages open communication with site personnel to resolve issues quickly and maintain compliance.
- If you have questions regarding stormwater compliance or best practices, contact stormwater@wcid17.org or the WCID No. 17 Stormwater Inspector directly.
HOW TO MINIMIZE POLLUTION ON CONSTRUCTION SITES
Protect any areas reserved for vegetation and preserve existing trees.
- Preserving mature trees minimizes the amount of soil that needs to be stabilized once construction is complete, and minimizes the amount of runoff during and after construction activity.
Protect construction materials from run on and run off
- At the end of every workday and during rain events, provide cover for materials that could leach pollutants.
Designate waste disposal areas
- Clearly identify and separate waste disposal areas for hazardous, construction, and domestic waste, ensuring to protect all areas from run on and run off.
Install perimeter controls around downhill boundaries
- Install perimeter controls such as mulch log or silt fence around the downhill boundaries of the site. Make sure to remove sediment once it has reached halfway up the control.
Install inlet controls
- Protect inlets with mulch sock, gravel barriers, sand/rock bags, or silt fencing to ensure contaminants do not flow into the inlet. For whichever chosen control, make sure to remove sediment once it has reached halfway up the control.
Install a concrete/stucco washout basin
- Designate a leak proof basin lined with plastic for washing out used concrete and stucco containers. NEVER wash excess stucco or concrete residue down a storm drain or into a stream.
Maintain a stabilized exit
- Minimize sediment track out from vehicles exiting your site by maintaining an exit pad made of crushed rock or a preconstructed track out control mat.
Stabilize site when necessary
- Immediately stabilize exposed portions of the site whenever construction work will stop for more than 14 days, even if work is only temporarily stopped.
