Air Permitting Consultants in Louisiana: Title V, PSD, Nonattainment NSR and Minor Source Permits

CK Associates prepares Title V (Part 70) permit applications and renewals for industrial facilities from its Baton Rouge office. Title V permits run for a fixed term of up to five years, and under the federal Part 70 rules a renewal application is timely only if it is submitted at least six months before the permit expires, so check the expiration date in your permit and start early. Your state can require more lead time than the federal minimum.

A PSD permit is generally required when a new major source, or a major modification at an existing one, would increase emissions above federal thresholds in an area that meets air quality standards. CK Associates prepares PSD permit applications and runs the applicability analysis first, so you know whether PSD is triggered before you commit to a project schedule.

Nonattainment New Source Review (NNSR) applies to new or modified major sources in areas that do not meet a National Ambient Air Quality Standard. CK Associates prepares NNSR permit applications, and because area designations change, it checks the current status of your parish or county before scoping the work.

CK Associates performs ambient air dispersion modeling for the National Ambient Air Quality Standards and air toxics standards as part of permit applications. Modeling is how a facility shows regulators that its emissions will not cause or contribute to a standard being exceeded.

CK Associates prepares state minor source air permit applications for facilities that do not need a major source permit. The team builds the emission calculations and supporting documents so the application is complete at submittal, which aims to reduce avoidable questions from the agency.

Timing depends on the permit type, the facility, how complete the application is and agency workload, so no consultant can promise a date. CK Associates works on what you can control: a complete application, accurate emission calculations and early communication with the agency.
