There are many projects that seek TDEC-APCD’s review through a request for environmental consultation. The term “environmental consultation” includes but is not limited to environmental review requests, phase I or II environmental site assessment investigations, or requests for information for projects in the scoping phase for planned preparation of an Environmental Assessment or Environmental Impact Statement pursuant to the National Environmental Policy Act (NEPA).1

What types of projects are suitable for environmental consultation from TDEC APCD?

The majority of environmental consultation requests submitted to APCD include projects involving construction or operation of a proposed air contaminant source, demolition or renovation of structures which may have asbestos containing materials during a proposed renovation or demolition project, construction of new road or highway projects including modifications to existing interstates within Tennessee and review of planning documents related to future interstate or highway road construction projects. Also, any project or activity that might create fugitive dust or emissions during the construction or site preparation phases or involve land clearing activities where open burning may be employed to dispose of wood waste and tree limb debris may be the subject of an environmental consultation request. Requests for consultation involving any of the aforementioned purposes may be submitted directly to Michelle W. Owenby in TDEC-APCD at Air.Pollution.Control@tn.gov. Written, electronic submittal of requests and supporting documentation are preferred.2

What should I include in my request to TDEC-APCD?

When submitting a request for environmental consultation to APCD, the following information is helpful:

  • Detailed description of project.
  • Property address, maps and property location.
  • Detailed description of any activities that may generate air pollutants including construction activities and land clearing operations including any proposed mitigation activities.
  • Timelines and urgency of the proposed project.
  • Please indicate if you will or already have prepared and submitted a formal NEPA review request to the required NEPA review depositories.

What should I expect to receive from TDEC-APCD?

APCD staff will review the project details and provide written comments on the potential air impacts and air related issues that were identified during review along with possible recommendations on methods to mitigate the air impacts identified. These methods may include specific reference to the applicable air regulations and acceptable practices to resolve the perceived concerns. If permits are potentially needed or required to be issued prior to commencing the proposed project, recommendations on the procedure to follow may also be provided.
