A new law will go into effect November 15, 2017 requiring farmers to monitor and report air emissions from their livestock, equine, and poultry farms if levels of certain substances exceed acceptable thresholds within 24-hour periods. Farmers have historically been exempt from this regulation.
The regulation is contained in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) section 103. In the spring of 2017 the U.S. Court of Appeals for the District of Columbia Circuit struck down the rule that allowed reporting exemptions for farms. As long as there is no further action by the Court to push back the effective date, farmers and operators of operations that house beef, dairy, horses, swine and poultry must begin complying with the reporting requirements on November 15, 2017.
“Farmers and operators, especially of sizeable animal operations that are likely to have larger air emissions, need to understand the reporting responsibilities,” Peggy Hall stated, who is an assistant professor and field specialist in Agriculture and Resource Law at The Ohio State University.
The Environmental Protection Agency (EPA) published interim guidance to assist farms with the new compliance obligations. The following summarizes the agency’s guidance:
What substances to report
The EPA specifically names ammonia and hydrogen sulfide as two hazardous substances commonly associated with animal wastes that will require emissions reporting. Each substance has a reportable quantity of 100 pounds. If a farm releases 100 pounds or more of either substance to the air within a 24-hour period, the owner or operator must notify the National Response Center. A complete list of hazardous substances and their corresponding reportable quantities is here￼.
Note that farmers do not have to report emissions from the application of manure, and fertilizers to crops or the handling, storage and application of pesticides registered under federal law. However, a farmer must report any spills or accidents involving these substances when they exceed the reportable quantity.
How to report
Under CERCLA, farm owners and operators have two compliance options—to report each release or to follow the continuous release reporting process:
For an individual release that meets or exceeds the reportable quantity for the hazardous substance, an owner or operator must immediately notify the National Response Center (NRC) by phone at 1-800-424-8802.
Continuous release reporting allows the owner or operator to file an “initial continuous release notification” to the NRC and the EPA Regional Office for releases that will be continuous and stable in quantity and rate. Essentially, this puts the authorities “continuously” on notice that there will be emissions from the operation within a certain estimated range. If the farm has a statistically significant increase such as a change in the number of animals on the farm or a significant change in the release information, the farm must notify the NRC immediately. Otherwise, the farm must file a one year anniversary report with the EPA Regional Office to verify and update the emissions information and must annually review emissions from the farm. Note that a farm must submit its initial continuous release notification by November 15, 2017.
No reporting required under EPCRA
The litigation that led to CERCLA reporting also challenged the farm exemption from reporting for the Emergency Planning and Community Right to Know Act (EPCRA). EPRCRA section 304 requires facilities at which a hazardous chemical is produced, used or stored to report releases of reportable quantities from the chemicals. However, EPA explains in a statement issued on October 25, 2017 that the statute excludes substances used in “routine agricultural operations” from the definition of hazardous chemicals. EPCRA doesn’t define “routine agricultural operations,” so EPA states that it interprets the term to include regular and routine operations at farms, animal feeding operations, nurseries, other horticultural operations and aquaculture and a few examples of substances used in routine operations include animal waste stored on a farm and used as fertilizer, paint used for maintaining farm equipment, fuel used to operate machine or heat buildings and chemicals used for growing and breeding fish and plans for aquaculture. As a result of this EPA interpretation, most farms and operations do not have to report emissions under EPCRA. More information on EPA’s interpretation of EPCRA reporting for farms ishere.
What should owners and operators of farms with animal wastes do now?
Review the EPA’s interim guidance on CERCLA and EPCRA Reporting Requirements, available here.
Determine if the operation may have reportable quantities of air emissions from hazardous substances such as ammonia or hydrogen sulfide. The EPA offers resources to assist farmers in estimating emission quantities, which depend upon the type and number of animals and type of housing and manure storage facilities. These resources are available here.
A farm that will have reportable emissions that are continuous and stable should file an initial continuous release notification by November 15, 2017. A guide from the EPA for continuous release reporting ishere. Make sure to understand future responsibilities under continuous release reporting.
If not operating under continuous release reporting, immediately notify the National Response Center at National Response Center (NRC) at 1-800-424-8802 for any release of a hazardous substance that meets or exceeds the reportable quantity for that substance in a 24-hour period, other than releases from the normal application or handling of fertilizers or pesticides.

Note that the EPA is seeking comments and suggestions on the resources the agency is providing or should provide to assist farm owners and operators with meeting the new reporting obligations. Those who wish to comment should do so by November 24, 2017 by sending an e-mail toCERCLA103.email@example.com￼.
