Local Limits
Municipalities develop and enforce local limits to:
- Ensure their municipal wastewater treatment plants comply with environmental standards
- Safeguard worker health and safety
- Protect wastewater collection and treatment physical assests including collection pipes and pump stations
Local limits reflect site-specific conditions including the number and types of industry, businesses and other non-domestic sources in a municipality's service area.
