General Information
Under the Urban Air Toxics Strategy EPA is developing standards to control toxic air pollutants from area sources. "Area" sources are those sources that emit less than 10 tons annually of a single hazardous air pollutant or less than 25 tons annually of a combination of hazardous air pollutants. All of the National Emission Standards for Hazardous Air Pollutant (NESHAP) rules are listed in one table. Here you will find in alphabetical order, the links to the final rules, latest fact sheets, and other pertinent information on each category, including both area sources and major sources.
The Clean Air Act (CAA) requires EPA to identify a list of at least 30 air toxics that pose the greatest potential health threat in urban areas.
The CAA also requires EPA to identify and list the area source categories that represent 90 percent of the emissions of the 30 urban air toxics associated with area sources and subject them to standards under the CAA (section 112(d)). Through three separate listings (including a list in the Urban Air Toxics Strategy), EPA has identified a total of 70 area source categories (PDF) which represent 90 percent of the emissions of the 30 listed air toxics. Of these 70 area source categories, 28 had been regulated by June 2007 and the remaining area source standards are under development. The EPA was put on a court ordered schedule to issue the area source rules listed under the Urban Air Toxics Strategy.
To find your delegated authority, please contact your Regional representative (PDF) (1pg, 44k). Some state contacts are listed in the Table of Specific State Contacts (PDF) (10pp, 119k), or if not listed, find your State representative through the map search at this link: http://www.4cleanair.org/contactUsaLevel.asp. Please note that every agency on the state/local website or the Table of Specific State Contacts, has not necessarily taken delegation of the area source program. Please check with the EPA regional representatives for clarification on how and where to send notifications and to determine your State contact. On June 4, 2010, EPA issued a guidance memo (PDF) on implementing the final area source rule intended for State and local agencies.

Resources to Help you Comply
Implementation tools can be found on the source category specific rule pages and/or listed below. Please note that not all source categories will need implementation tools. Development of tools will be based on the complexity of the rule.
Where should I send Notifications or Reports required by Subpart HHHHHH at 40 CFR §63.11175 - 63.11176 (i.e., the Initial Notification, Notification of Compliance Status, and Annual Notification of Changes Report), or the Petition for Exemption? See State Delegation PDF(2pp, 21k)
Initial Notification/Compliance Examples
Important Note: There is no specific template required for the initial notification. The owner/operator simply needs to provide to their EPA Regional Office the information specified in section 63.11553 of the rule ("What are my notification, reporting, and recordkeeping requirements"). For States where the rule has been delegated (See State Delegations ), the initial notification needs to go to the EPA Regional Office and the delegated state or delegated local permitting authority. You may submit the information required in another format. It is highly recommended that you talk with your permitting authority before using any of these examples as potential templates.
