Report Illicit Discharge: 214.509.4512
What is illicit discharge?
Anything entering the storm sewer system that is not 100% storm water is an illicit discharge and is expressly prohibited from entering the system. Storm drains are separate from the sanitary sewer system, which means any polluted water that enters the storm drain will flow directly into local creeks and waterways. To protect the quality of our streams and public health, we encourage you to report illicit discharges.
When reporting illicit discharge, please include as much detail as possible, such as: a description of what is being discharged, a license plate/vehicle description, date and time of the violation, street location, your name and number (can remain anonymous).

TPDES Annual Report
Allen is classified as an urbanized area by the Environmental Protection Agency (EPA), and therefore must adhere to the Texas Pollutant Discharge Elimination System (TPDES) - a regulatory program to control discharges of pollution onto surface waters of the United States.
Each year the City of Allen provides an annual report of its TPDES permit to the Texas Commission on Environmental Quality. This report includes our progress toward achieving program benchmarks and permit compliance.
Erosion and construction
View erosion control design plans - Erosion control and stabilization measures must be initiated immediately in portions of the site where construction activities have temporarily ceased and will not resume for a period exceeding 14 calendar days. Stabilization measures that provide a protective cover must be initiated immediately in portions of the site where construction activities have permanently ceased.
The term "immediately" is used to define the deadline for initiating stabilization measures. In the context of this requirement, "immediately" means as soon as practicable, but no later than the end of the next work day, following the day when the earth-disturbing activities have temporarily or permanently ceased.
Stormwater Management Plan
The City of Allen has submitted its permit renewal application to the Texas Commission on Environmental Quality (TCEQ). If you are interested in the submitted Stormwater Management Plan and corresponding Notice of Intent (NOI), please view the draft Stormwater Management Plan below. At this time, as with many other municipalities in North Texas, the City has not received approval for our renewed permit submission.
