Environmental Protection Pennsylvania 4 Minutes Read ยท published March 01, 2026 Flag of Pennsylvania

Allentown, Pennsylvania manages stormwater runoff and pesticide applications through city programs and by following state standards to protect waterways and public health. This guide explains how local rules affect homeowners, landscapers, and businesses in Allentown, describes enforcement and penalties, and shows how to apply for permits, submit complaints, and follow best practices to reduce runoff and avoid illegal pesticide discharge.

Scope & Key Rules

The City of Allentown regulates stormwater to control pollutant discharge to local streams and the Lehigh River, and enforces restrictions on pesticide use where it contributes to runoff or affects public rights-of-way. City stormwater requirements implement the municipal separate storm sewer system (MS4) obligations and reference state pesticide and water quality rules for application and disposal.

Always check permit conditions before applying pesticides on properties that drain to storm drains.

How the Rules Apply

  • City-regulated discharges to the storm sewer system are controlled; unauthorized pollutant discharge is prohibited.
  • Pesticide application that causes runoff into storm drains or surface waters may trigger enforcement under city code and state law.
  • Complaints or reports of spills and illegal applications are handled by the Public Works/Stormwater division and Code Enforcement.

Penalties & Enforcement

The city enforcer for stormwater and related violations is the City of Allentown Public Works Department, Division of Stormwater, together with Code Enforcement for property-related violations. Enforcement can include fines, stop-work orders, corrective action orders, and referral to court for injunctive relief or civil penalties. For pesticide licensing and misuse, Pennsylvania Department of Agriculture rules and enforcement may also apply. [1][2]
