10.3 Incident Reporting Requirements to TDA & Regulatory Agencies

Incident Reporting Requirements to TDA & Regulatory Agencies

When a pesticide spill, explosion, fire, or transportation collision occurs in Tennessee, environmental safety relies on rapid communication between the applicator and regulatory authorities. Both federal statutes—such as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Emergency Planning and Community Right-to-Know Act (EPCRA)—and state laws—specifically the Tennessee Pesticide Control Act—mandate strict, prompt incident reporting. Failing to report a qualifying chemical release can result in severe criminal penalties, civil fines, and license revocation.

Understanding Reportable Quantities (RQ)

Under federal environmental law, EPA establishes a specific Reportable Quantity (RQ) for hundreds of hazardous chemical active ingredients. An RQ is a legal threshold measured in pounds. If a spill releases an amount of active ingredient equal to or exceeding its listed RQ into the environment within a 24-hour period, the applicator is legally mandated to report the release immediately.

How to Determine a Product's RQ

1. Inspect Safety Data Sheets (SDS): Section 15 (Regulatory Information) lists CERCLA/EPCRA RQs for all formulation components.
2. Check Container Labels: Products packaged in quantities exceeding their RQ must state the designation "RQ" on the shipping paper and container label.
3. Consult 40 CFR Part 302: EPA's master list of hazardous substances.

Active Ingredient Calculation Example

Pesticide formulations consist of active ingredients (a.i.) dissolved or suspended in inert carriers. RQ calculations must be based on the pure active ingredient weight, not the total gross weight of liquid product.

• Scenario: An applicator spills 15 gallons of an insecticide containing 4 lbs of chlorpyrifos active ingredient per gallon.
• Calculation: $15 \text{ gallons} \times 4 \text{ lbs a.i./gal} = 60 \text{ lbs of active chlorpyrifos}$.
• Threshold: Chlorpyrifos has a CERCLA RQ of 1 pound.
• Determination: Spilling 60 lbs of active ingredient far exceeds the 1 lb RQ threshold. Immediate federal, state, and local emergency reporting is legally mandatory.

Mandatory Reporting Agencies & Contact Directories

A single spill incident may require notifications to multiple government agencies depending on the release volume, location, and environmental media affected.

1. National Response Center (NRC)

The NRC is the primary federal point of contact for chemical spills, operated 24/7 by the U.S. Coast Guard for the EPA. Federal law requires calling the NRC (1-800-424-8802) immediately whenever:

• A spill equals or exceeds the product's federal Reportable Quantity (RQ).
• Any pesticide spill enters surface water, roadside ditches, storm sewers, or navigable streams, regardless of the quantity spilled.

2. Tennessee Department of Agriculture (TDA)

As the state licensing and enforcement authority under the Tennessee Pesticide Control Act, the TDA Consumer and Industry Services Division (1-615-837-5148) must be notified immediately regarding:

• Any commercial or agricultural pesticide spill resulting in soil or water contamination.
• Transportation accidents involving vehicles carrying commercial pesticide supplies.
• Pesticide storage facility fires, chemical explosions, or structural collapse.
• Incidents resulting in human chemical exposure, hospitalization, or non-target crop/livestock damage.

3. SERC & LEPC Coordination

Under EPCRA Section 304, any RQ release requires immediate notification to:

• State Emergency Response Commission (SERC): In Tennessee, the Tennessee Emergency Management Agency (TEMA) serves as the SERC contact (1-800-262-8300).
• Local Emergency Planning Committee (LEPC): Contact the local county emergency management director or emergency communications center (911).

Information Required When Making an Incident Report

When calling emergency response hotlines, applicators must be prepared to provide clear, accurate details. Have the product SDS and container label in hand before placing the call.

1. Reporter Contact Info: Full name, title, company name, callback phone number, and physical location.
2. Location Details: Exact street address, mile marker, GPS coordinates, and proximity to sensitive receptors (e.g., schools, streams, sinkholes, residential areas).
3. Chemical Identity: Commercial brand name, EPA Registration Number, active ingredient(s), and manufacturer name.
4. Release Metrics: Estimated total volume spilled, active ingredient weight released, time and duration of release, and whether the leak is ongoing.
5. Environmental Media Impacted: Media contaminated (e.g., concrete pad, surface soil, storm drain, creek, air).
6. Incident Cause & Response Status: Cause of release (e.g., equipment collision, hose rupture), weather conditions (wind speed/direction, rain), injuries, and ongoing mitigation actions taken under the 3 C's.

Emergency Technical Assistance: CHEMTREC

During chemical transportation emergencies, applicators can call CHEMTREC (Chemical Transportation Emergency Center) at 1-800-424-9300. Operating 24 hours a day, CHEMTREC provides:

• Immediate chemical hazards verification and SDS technical guidance.
• Direct telephone linkage with pesticide manufacturer toxicologists and chemical engineers.
• Guidance on chemical neutralizers, fire control methods, and spill containment.

Note: Calling CHEMTREC does not fulfill legal spill reporting obligations to the NRC, TDA, SERC, or LEPC. CHEMTREC is an emergency assistance service, not a government regulatory authority.

Post-Incident Written Reports & Compliance Records

Following verbal emergency phone calls, federal and Tennessee state laws mandate submission of formal written follow-up reports:

• SERC / LEPC Written Follow-up: Must be submitted within 30 days detailing final release estimates, actual health effects, cleanup actions, and long-term preventive measures.
• TDA Incident Documentation: Retain all spill logs, shipping manifests, waste disposal receipts, and incident notes in commercial applicator compliance files for at least 2 years for inspection by TDA officials.
