Supporting the Industry Behind Texas Infrastructure
Aggregate materials are fundamental to the construction and maintenance of infrastructure across Texas. Crushed stone, sand, gravel, and other materials support the development of roads, bridges, commercial properties, utilities, and public infrastructure.
As Texas continues to grow, demand for these materials remains an important part of the state’s construction and development activity. Aggregate producers and concrete facilities help meet that demand, but operating these facilities also involves navigating a range of environmental requirements.
From obtaining the appropriate permits before operations begin to maintaining compliance throughout the life of a facility, environmental considerations can affect daily operations, expansion plans, and long-term business decisions.
Understanding these requirements early and maintaining an effective environmental management program can help facility owners address potential issues before they become larger operational or regulatory challenges.
Air Quality and Permitting Requirements
Air quality is one of the most significant environmental considerations for aggregate and concrete operations.
Activities such as crushing, screening, conveying, material handling, loading, and stockpiling can generate particulate matter and other air emissions. Depending on the facility’s equipment, production capacity, processes, and operating conditions, applicable air authorizations may be required through the Texas Commission on Environmental Quality (TCEQ).
Air permitting considerations may include:
Air Permit Applicability: Evaluating facility operations and equipment to determine applicable permitting requirements and authorization pathways.
Air Permit by Rule (PBR): Determining whether qualifying operations may be authorized under an applicable PBR and whether all associated conditions can be met.
Standard Permits and Other Authorizations: Evaluating whether a Standard Permit or another authorization is appropriate based on the facility’s operations and regulatory applicability.
Emissions Evaluations: Assessing potential emissions from equipment and processes to support permitting decisions and compliance demonstrations.
Opacity and Visible Emissions: Evaluating visible emissions and applicable opacity requirements, including Method 9 observations when appropriate.
Air permitting is not a one-time consideration. Changes to equipment, production capacity, facility layout, or operating practices may affect existing authorizations and should be evaluated before modifications are implemented.
Stormwater Management at Aggregate Facilities
Stormwater management is another important component of environmental compliance for aggregate and concrete facilities.
Outdoor industrial activities can expose stormwater to materials and potential pollutants. Depending on the facility’s industrial activities and applicable permit requirements, stormwater discharges may be regulated under TCEQ’s Texas Pollutant Discharge Elimination System (TPDES) Multi-Sector General Permit (MSGP).
Aggregate facilities commonly need to evaluate stormwater considerations associated with:
- Material storage and stockpiling areas.
- Crushing, screening, and processing equipment.
- Equipment maintenance and fueling areas.
- Loading and unloading locations.
- Waste storage and handling areas.
- Drainage patterns, stormwater outfalls, and discharge locations.
Facilities covered under the applicable MSGP must develop and implement a Stormwater Pollution Prevention Plan (SWP3) that identifies potential pollutant sources and establishes appropriate management practices.
An effective stormwater program may include SWP3 development and updates, facility inspections, visual examinations, applicable monitoring, corrective actions, and required documentation.
As operations change, stormwater programs should be reviewed to ensure they accurately reflect current facility conditions and activities.
Water Resources and Environmental Constraints
Aggregate operations may involve activities that intersect with wetlands, streams, drainage features, and other water resources.
These considerations can be particularly important when evaluating new sites, expanding existing operations, developing access roads, or modifying processing and material storage areas.
Depending on the location and scope of proposed activities, environmental evaluations may need to address:
Wetlands and Other Waters: Identifying potentially regulated aquatic resources and evaluating whether proposed impacts may require additional permitting or agency coordination.
Drainage and Floodplain Considerations: Evaluating site drainage, floodplain conditions, and potential impacts associated with facility development or expansion.
Biological Resources: Identifying potential habitat for protected species or other sensitive biological resources that may influence site development.
Environmental Site Conditions: Reviewing historical site uses and existing environmental conditions to identify potential concerns before acquisition or construction.
Early environmental assessments can help facility owners and developers understand site constraints, evaluate alternatives, and make more informed decisions about future operations.
Environmental Compliance Throughout Facility Operations
Obtaining the appropriate environmental authorizations is only one part of operating an aggregate or concrete facility. Maintaining compliance requires ongoing attention to permit conditions, operational practices, inspections, and documentation.
Facilities may need support with:
- Reviewing existing environmental permits and registrations.
- Evaluating operational changes for regulatory applicability.
- Maintaining stormwater management programs.
- Conducting inspections and monitoring.
- Evaluating visible emissions and applicable opacity requirements.
- Addressing agency notices of violation (NOVs).
- Maintaining environmental records and compliance documentation.
When potential compliance issues are identified, understanding the underlying cause and determining appropriate corrective actions are important steps toward resolving them.
An ongoing environmental management approach can help facilities stay informed about applicable requirements, identify potential gaps, and maintain consistency as operations evolve.
Environmental Due Diligence for Aggregate Site Acquisition and Expansion
Environmental considerations also play an important role when acquiring, developing, or expanding aggregate facilities.
Before purchasing an existing operation or investing in a new site, buyers and developers should understand the property’s environmental conditions, existing permits, and potential regulatory obligations.
Environmental due diligence may involve reviewing historical property uses, existing environmental reports, regulatory records, permits, and known or potential environmental concerns.
For aggregate and concrete operations, this review may also include evaluating:
- Existing air permits, registrations, and operational authorizations.
- Stormwater permit coverage and SWP3 documentation.
- Outstanding compliance issues or agency correspondence.
- Historical industrial activities and potential contamination concerns.
- Wetlands, water resources, and other site constraints.
- Potential environmental requirements associated with future expansion.
Identifying these considerations before a transaction or development decision can help buyers and facility owners better understand potential environmental risks and future obligations.
If an investigation identifies potential contamination or other environmental concerns, additional assessment or corrective action may be necessary.
