EPA has issued a proposed rule that would require many non-transportation-related facilities to develop a Facility Response Plan under the Clean Water Act, based on planning for worst-case scenario discharges. This significantly increases the number of facilities who may need a Facility Response Plan and increases the number of hazardous substances to be considered.

TL;DR: EPA expanded Facility Response Plan requirements to facilities in crop production, mining, utilities, food manufacturing, chemical manufacturing, and primary metals based on three criteria: storage exceeding 10,000 times reportable quantity, location within 0.5 miles of navigable water, and substantial harm potential (discharge impact on water systems or wildlife).

⚠️ What’s at stake: Facilities discovering they’re within the expanded scope must develop worst-case scenario response plans that meet EPA technical specifications. Non-compliance with Facility Response Plan requirements triggers CWA penalties of $25,000–$75,000+ per violation, plus facility-specific enforcement action and operational restrictions.

What Industries are Affected?

The new rule would apply to a wide range of NAICS code groups including Crop Production, Oil and Gas Extraction, Mining, Utilities, Food Manufacturing, Chemical Manufacturing, Plastics and Rubber Products, Primary Metal Manufacturing, Warehousing, Hospitals, and many more.

How Do You Know if It Affects Your Company?

Three criteria: Maximum Capacities (does your storage exceed 10,000 times the reportable quantity), Location (within half mile of navigable water), and Substantial Harm Criteria (ability to adversely impact water systems, fish, wildlife, or public receptors, or having had a reportable discharge within 5 years).

If your facility processes chemicals, stores hazardous substances, or operates within 0.5 miles of navigable water in Kansas, Oklahoma, Texas, or Missouri, the Facility Response Plan expansion likely affects you. iSi Environmental evaluates FRP applicability and develops worst-case scenario response plans.

💰 The cost of non-compliance: Facilities required to develop Facility Response Plans but operating without one face CWA penalties of $25,000–$75,000 per violation. A facility experiencing a reportable discharge without a current FRP in place faces additional penalties for preparedness failure, plus mandatory plan development, cleanup oversight, and operational restrictions.

Frequently Asked Questions

Q: What is a Facility Response Plan under the Clean Water Act?

A Facility Response Plan is a worst-case scenario planning document required under the Clean Water Act that details how a facility would respond to a worst-case scenario discharge of hazardous substances into navigable waters. The plan must address spill prevention, mitigation, cleanup, and emergency response procedures.

Q: Which facilities must develop a Facility Response Plan under the proposed rule?

Under EPA’s proposed expansion, facilities in numerous industries including Crop Production, Oil and Gas Extraction, Mining, Utilities, Food Manufacturing, Chemical Manufacturing, Primary Metal Manufacturing, Hospitals, and Warehousing may be required to develop a Facility Response Plan. The specific requirement depends on storage capacities, proximity to navigable water, and history of reportable discharges.

Q: What are the three main criteria EPA uses to determine if my facility needs a Facility Response Plan?

EPA applies three criteria: Maximum Capacities (whether your facility stores more than 10,000 times the reportable quantity of hazardous substances), Location (whether the facility is within half a mile of navigable water), and Substantial Harm Criteria (whether discharge could adversely impact water systems, wildlife, or public receptors, or if there was a reportable discharge in the past five years).

Q: What should I do if I think my facility might be affected by the proposed rule?

iSi Environmental recommends reviewing your facility’s storage quantities, proximity to navigable waters, and discharge history against EPA’s criteria. Contact iSi Environmental for assistance in determining compliance obligations and developing or updating your Facility Response Plan.


The EPA’s Facility Response Plan expansion moved these requirements from a narrow set of industries to a broad universe of manufacturers, utilities, and agricultural operations—especially those in states with navigable water proximity. iSi Environmental assesses FRP applicability and develops worst-case scenario response plans for facilities in crop production, mining, food manufacturing, chemical manufacturing, and primary metals.
