Hazardous Metals in Stormwater – Texas (TCEQ) Requirements

As general permits for stormwater discharges are revised, States will attempt to address requirements for impaired waters into the permit requirements. How these requirements are expressed in the permit varies widely from State-to-State. Some States have developed requirements which promote pollution prevention measures.

As one example, the State of Texas has detected levels of selected heavy metals in surface waters which are of concern, and has promulgated numeric discharge standards for “hazardous metals” into the industrial stormwater permit. However, the Texas Commission on Environmental Quality (TCEQ) approach is to allow facilities to do a self-assessment for sources of hazardous metals and implement pollution prevention measures to avoid the higher costs of hazardous metal sampling and testing. To be exempted, facilities must certify that:

• Facility does not use a raw material, produce an intermediate product, or produce a final product that contains one of the listed hazardous metals, or


• Any raw materials, intermediate products, or final products which contain a hazardous metal are never exposed to stormwater or runoff, or


• Facility collects and analyses stormwater samples from the facility and the results indicate that hazardous metal(s) are not present in detectable levels.
  

Waivers may be obtained on a metal-by-metal basis, or on an outfall-by-outfall basis. A waiver from hazardous metals monitoring does not exempt the facility from other benchmark monitoring requirements which may apply. [Read more about benchmark monitoring]

Knowledge Based SWPPP Training – Texas (TCEQ) Construction Permit Example

Stormwater training requirements in most general permits are prescriptive and require specific documentation to demonstrate compliance. If documentation can be produced that shows an employee received appropriate training, the permit requirement is considered to be met. Most often, training rooster sign-in sheets are used as documentation.

An alternate requirement for SWPPP training is “knowledge-based”, meaning that compliance or noncompliance is determined by what the employee knows and not what training courses the employee has attended.

An example of knowledge-based training requirements is found in the Texas Commission on Environmental Quality (TCEQ) general permit for construction stormwater discharge (Permit # TXR150000). In this permit, “training” is only required for personnel responsible to conduct site inspections. No specific training needs to be documented. However, inspectors must be “knowledgeable of [requirements of the] general permit, familiar with the construction site, and knowledgeable of the SWPPP for the site”. Regardless of any specific training inspectors can show, if they can not meet these performance criteria, they may not be considered qualified to conduct inspections.

Although knowledge-based training requirements have the advantage that no specific training documentation is needed, they also require a higher standard for actual knowledge. Employers need to assure that their employees know what they need to know.


Caltha LLP has several training programs created to help Texas contractors meet the performance standards of the TCEQ construction site discharge permit, including several customized programs to meet the requirements of small and medium size contractors in all States.
