Who Needs One?

The operator of a ready mix concrete facility with discharges of washwater, stormwater, or a no-discharge recycle system must file for coverage under the Division of Water Pollution Control General NPDES Permit for Discharges of Storm Water Runoff and Process Waste Water Associated with Ready Mix Concrete Facilities

What Information Must I Provide?

Applicants must submit the following information at least 30 days prior to any discharge of process waste water or storm water runoff to the waters of the State. An original Notice of Intent (NOI) and required attachments must be sent to the address on the NOI form. Facilities that discharge storm water through large or medium municipal separate storm sewer systems (MS4) in Memphis, Nashville/Davidson County, Knoxville and Chattanooga must also submit a signed copy of the NOI to the operator of the MS4.

  • A completed "Ready Mix Concrete Plant Notice of Intent." This form includes name, mailing address, existing NPDES permit number (if applicable) and location of the facility; name of the owner/operator, mailing address, contact person and phone number; type of discharge, name and location, by river mile of the receiving waters; description of wastewater treatment systems used at the facility; area in square feet or acres of the facility; list of locations, other than the plant site or active job site, where the permittee’s concrete trucks are washed out.
  • A facility location map with boundaries that extend at least one mile beyond the site property and identify specific locations of the discharges.

If an operator will be installing or upgrading a wastewater treatment system then plans and specifications for construction must be submitted to the Division at least 90 days before any discharge of process wastewater or storm water runoff to the waters of the state occurs. The plans shall be submitted to division’s Environmental Field Office responsible for the county where the facility is located.

How Will My Application Be Processed?

The Division will review the NOI and attachments for completeness and accuracy. Within 30 days after the Division receives a complete and accurate NOI, the Division will send the permittee a notice of coverage under the general permit. Coverage under the general permit is not transferable to new facility owners.

What Fees Are Required?

Permit Application Fee: none

Annual Permit Fee: $250

Plans Review Fee: $250

What Are My Rights and Responsibilities After the Permit is Approved?

A permittee who has submitted an NOI and received permit coverage has the duty to comply with all provisions of the general permit and applicable rules and regulations. Coverage under the NPDES general permit does not relieve the permittee of the responsibility for damages to surface or ground water. The permittee must notify the Division as soon as possible of planned alteration or additions to the permitted facility or of any change in mailing address. The permittee is responsible for monitoring discharge, developing a storm water pollution prevention plan, reporting data, keeping records, and placing signs at discharge outfalls as detailed in the general permit. If the facility experiences any emergency that could impact the waters of the state, they must notify the Division as detailed in the general permit.

What Are the Division’s Rights and Responsibilities After the Permit is Approved?

The Division has the right to revoke, suspend, or deny the issuance of a permit to any applicant who violates the state statutes, departmental regulations, or terms of the general permit. The Division has the right to inspect the site, monitoring equipment, and associated records at reasonable times. They also have the right to sample any discharge. Any person who violates or fails to comply with the state statutes, rules, or regulations may be subject to criminal and/or civil penalties.

Whom Do I Contact For Applications, Assistance and Other Information?

Applicants may obtain applications and assistance from the Division of Water Pollution Control, Central Office or any TDEC Environmental Field Office, or use the form above.
