(2) What is considered to be a "safe distance" from a Class I area? (3) Do the 50-ton source requirements apply to nonattainment areas, as well as to attainment areas, and does the offset requirement apply to such a source?

(pdf) | Region 6 | Meiburg, Stanley | Addresses multiple questions related to the nonattainment NSR program including the following: (1) Does any increase in emissions at a major source trigger the de minimis threshold test? Is there a lower cutoff? (2) What is the exact definition of the 5-year period for the de minimis threshold test? (3) Do major sources, such as asphalt concrete plants, that move often within nonattainment areas, as well as in and out of nonattainment areas, require a nonattainment permit each time they move? (4) TACB states that the definition of major source it serious and severe ozone nonattainment areas in Sections 182 (c) and (d)could be interpreted to include fugitives emissions. They would like to extend this definition to marginal and moderate ozone nonattainment areas for the purposes of Consistency. (5) For sources which trigger review for nitrogen oxides (NOX) under both nonattainment review and PSD, TACB proposes to conduct a combined review which will include nonattainment review enhanced by NOX increment modeling. (6) What are applicants and permit engineers expected to do when implementing lowest achievable emission rate (LAER)? |

Return to Policy & Guidance Document Index
The “Relevant Guidance” index includes a collection of documents issued by EPA organized by topic area. These documents include memoranda, letters, orders, and other types of EPA actions that may provide guidance in one or more forms, such as an adjudication, statement of policy, interpretation of statutes or regulations, or technical information. Each collection is intended to be representative of EPA statements on the topic, but it may not be a complete listing of such statements. The collection does not reflect topic-specific statements that have been expressed by EPA though published rule preambles and Title V petition orders, nor does it include EAB decisions. Each document in the collection speaks for itself, and the inclusion or exclusion of a document in the collection is not intended by EPA to communicate anything more than what is expressed within each document. EPA makes no independent representations on this website as to the extent to which any document in the collection reflects EPA’s current views on the topic, is a final action by EPA, or has any legal effect or precedential weight. Readers are advised to review the documents in the collection and conduct their own assessment of such considerations based on the content of each document and other documents in the collection. Some of the information or views included in the documents may be affected by subsequent changes to the referenced statutory or regulatory language or by court decisions. In addition, many of the statements in these documents are based upon the federal regulations which may differ from rules that govern federally-approved programs. Permitting authorities are advised to consult with their EPA Regional Offices if there is a question as to the relevance of a particular statement to their NSR program.
