CERCLA Hazardous Substances - 40 CFR part 302.4 (47 pp, 414 K, About PDF) 
CERCLA Release Reporting Requirements - 40 CFR part 302.6 (3 pp, 199 K, About PDF)

NRC: 1-800-424-8802 or 202-267-2675.

The following categories are exempt from release reporting:

• Normal application of fertilizers.
• Application, handling and storage of a registered pesticide by an agricultural producer.
• Natural gas, natural gas liquids, liquified natural gas, or synthetic gas usable for fuel.
• Petroleum products not specifically listed or designated as a hazardous substance. For example, gasoline or diesel fuel.

Clean Air Act

Particulate Matter (PM) National Ambient Air Quality Standards (NAAQS):  Some agricultural sources in PM10 nonattainment areas are impacted by PM10 standards to satisfy reasonably available control measures and control technologies requirements. PM2.5 SIPs will be due no later than April 2008.  In those SIPs, states will evaluate, on an area by area basis, whether there is a need to regulate PM 2.5 or PM 2.5 precursors from ag related sources.

Ozone  NAAQS:  Some agricultural areas are impacted by these standards which primarily deal with nitrogen oxides (NOX) and Volatile Organic Compound (VOC) emissions.  These have the potential to impact some animal production practices and have potential to impact pesticide application practices.  NOX emissions from stationary engines could be impacted by these standards and the corollary implementation rules.

Comply with your state's State Implementation Plan (SIP).

Farms located in air “non-attainment” areas

Air Program/Asbestos: The Asbestos National Emissions Standards for Hazardous Air Pollutants (NESHAP) is intended to minimize the release of asbestos fibers during activities involving the handling of asbestos. Accordingly, it specifies work practices to be followed during renovations of buildings.

Building renovation/demolition:

Renovations of buildings which contain a certain threshold amount of friable asbestos, and during demolitions of all structures, installations, and facilities (except apartment buildings that have no more than four dwelling units).

Title V Permit

The source must apply for a permit if aggregate of non-fugitive emissions of any regulated pollutant exceeds 100 tpy. Also, generally, sources that are major under Section 112, Section 302, or Part D of title I are also considered major under title V and required to obtain a title V permit.

Any stationary source.

In determining major source status, emissions from all operations at the farm must be considered, including stationary sources such as boilers and internal combustion engines but excluding mobile sources such as tractors.  For farms, fugitive emissions are not included in determining whether a source is major. Fugitive emissions are those "...which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening."

New Source Review / Prevention of Significant Deterioration permit

The source must apply for a permit if aggregate of non-fugitive emissions of any regulated pollutant exceeds a certain threshold amount depending on the attainment/non-attainment status of the area and on the pollutant. This requirement applies to new sources as well as to major modifications of sources.

Any stationary source.

In determining major source status, emissions from all operations at the farm must be considered, including stationary sources such as boilers and internal combustion engines but excluding mobile sources such as tractors.  For farms, fugitive emissions are not included in determining whether a source is major. Fugitive emissions are those "...which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening."

National Emission Standard for Hazardous Air Pollutants (HAP) – 40 CFR Part 63, subpart ZZZZ/Standards of Performance for Stationary Spark Ignition Internal Combustion Engines (New Source Performance Standards – 40 CFR Part 60, subpart JJJJ)/Standards of Performance for Stationary Compression Ignition Internal Combustion Engines (New Source Performance Standards – 40 CFR Part 60, Subpart IIII)

The engine must comply with this regulation if it is located at a facility whose emissions are at least 10tpy of one HAP or 25tpy of total HAP and if the engine itself is at least 500 HP.

Stationary or reciprocating internal combustion engines (RICE).

Mobile Source Program

On and Off-Road equipment:

Farm vehicles, engines, equipment and fuels.

General duty for chemical accident prevention

Owners and operators of all facilities that use, handle, or store extremely hazardous substances in any quantity, including farms handling ammonia, have a general duty to identify hazards, design and maintain a safe facility taking steps to prevent releases, and minimize the consequences of accidental releases that do occur.

Any farm.

Risk Management Program and Plan (RMP)

Farms that handle more than a threshold quantity of certain toxic and/or flammable substances must implement a chemical accident program and prepare and submit a Risk Management Plan (RMP) to EPA.

Excluded substances are:

• Ammonia, used as an agricultural nutrient, when held by a farmer.
• Listed flammable substances used on-site as a fuel.

Farm Equipment Standards

Boilers - There are two types of air emission regulations for boilers.

Engines - Air quality requirements vary for stationary engines, depending on whether the engine is new or existing, where the engine is located, and what type of ignition system is used.

Farms with boilers (steam generating units).


Farms with stationary internal combustion engines.

Hazardous Chemical Inventory Reporting (Tier I & Tier II)

Submit a hazardous chemical inventory form (also known as Tier II) to the State Emergency Response Commission (SERC), Local Emergency Planning Committee (LEPC) and the local fire department, annually, by March 1.

The following substances are exempt from reporting:

• Pursuant to EPCRA section 311(e)(5), substances used in routine agricultural operations are exempt from reporting.

Any farm handling more than a threshold quantity of OSHA hazardous chemicals, which includes EPCRA extremely hazardous substances (EHSs) and non-EHSs)

Emergency release reporting

• Natural releases from farming land disturbance activities

Any farm that releases more than a reportable quantity or more of an extremely hazardous substance or a CERCLA hazardous substance.

Emergency Planning Notification

Notify State Emergency Response Commission (SERC) and Local Emergency Planning Committee (LEPC) if you have an EPCRA EHS at or above its threshold planning quantity (TPQ).  Designate a facility emergency coordinator to participate in local emergency planning process and provide requested any information necessary for development of local emergency plan.

The list of EHSs and their TPQs can be found at 40 CFR 355, Appendix A and B. 

Any farm that has an EPCRA EHS present at or above its threshold planning quantity.

There are no exclusions or exemptions for farms for this requirement.

Lead-Based Paint

EPA’s Lead Renovation, Repair and Painting Rule (RRP Rule) requires that firms performing renovation, repair, and painting projects that disturb lead-based paint in homes, child care facilities and pre-school built before 1978 have their firm certified by EPA (or an EPA authorized state), use certified renovators who are trained by EPA-approved training providers and follow lead-safe work practices.
