Understanding the Environmental Agency Regulatory Position Statement for Concrete Wash Water - RPS 287

The Regulatory Position Statement (RPS) 287 provides guidance for managing water containing concrete at construction sites in a manner that is environmentally responsible and compliant with regulations.

Here's a detailed summary of the key points:

Purpose and Scope

• Objective: The RPS 287 outlines conditions under which construction sites can treat and use water that has come into contact with concrete without an environmental permit. This is aimed at preventing pollution while facilitating construction activities.

• 
  

Conditions for Treatment and Use

1. Treatment Process:

   • Neutralisation: Water must be treated to neutralise its pH, typically through the addition of acids or carbon dioxide, to ensure it is safe to release into the environment or reuse on site.

   • Sediment Removal: Ensure that any sediments or solids are removed from the water before it is discharged or reused.

2. Use of Treated Water:

   • On-Site Reuse: Treated water can be reused on the same construction site, provided it meets the required safety standards.

   • Discharge to Surface Water or Sewer: If the treated water is to be discharged, it must meet specific environmental standards to prevent pollution.

     
     

Compliance and Monitoring

1. Environmental Standards:

   • Water Quality Testing: Regular testing is required to ensure that the treated water complies with environmental standards, particularly concerning pH levels and the absence of harmful substances.

2. Record Keeping:

   • Maintain detailed records of the treatment processes, water quality tests, and the quantities of water treated and reused or disposed of. These records should be available for inspection by regulatory authorities.

     
     

Exemptions and Limitations

• Exemption from Permit: This RPS allows construction sites to operate without a formal environmental permit for water treatment, provided all conditions are met.

• Non-Compliance Risks: If the conditions of the RPS are not met, the site may need to obtain a permit or cease operations, and there is a risk of regulatory action for environmental harm.

  
  

Review and Expiry

• Regular Review: The RPS is subject to regular review and updates to ensure continued compliance with environmental laws and standards.

• Expiry Date: Users should be aware of the RPS's expiry date, after which a new policy or extension may replace it.

  
  

Conclusion

RPS 287 provides a framework for the responsible treatment and use of water containing concrete at construction sites. By following the outlined conditions, construction projects can minimise environmental impact, reduce regulatory burdens, and maintain operational efficiency. It is essential for site managers to stay informed about the specific conditions and maintain compliance through ongoing monitoring and record-keeping.
