Air Quality: Permit to Construct
| |
| |
| An air quality permit to construct
(PTC) is required prior to construction or modification of buildings,
structures, and installations that emit, or may emit, pollutants into
the air. Procedures and requirements for PTCs are found in Sections
201-228 of the Rules
for the Control of Air Pollution in Idaho. |
| |
| Who Needs a PTC? |
Idaho's air pollution control
rules require the owner or operator of any stationary source that
emits or may emit air pollution to obtain a PTC from DEQ before
beginning construction or modifying the source (unless the activity
is specifically exempt from the need to obtain a permit).
A stationary
source is defined
as "any building, structure, emissions unit, or installation
which emits or may emit any air pollutant."
Commencement
of construction or modification is, in part, defined
as "to engage in a continuous program of construction or
modification, or to engage in a program of planned grading, dredging,
or land filling, specifically designed for the stationary source
or facility in preparation of the fabrication, erection, or installation
of the building components of the stationary source or facility."
PTCs are required for certain
portable equipment as well, such as generators, crushing equipment,
asphalt plants, and concrete batch plants.
|
| |
Exceptions |
Portable rock crushers that meet
certain criteria may operate under a permit by
rule instead of a PTC. Petroleum (gasoline diesel and aviation
fuel) remediation projects that meet certain design specifications
have been specifically exempted from the need to obtain a PTC. Mobile
internal combustion engines (cars, trucks, and heavy construction
equipment) are not considered stationary sources.
|
| |
| Application Forms, Checklists, and Guidance |
PTC application forms, checklists, and guidance are provided for sources requiring this permit. Applicants are encouraged to contact the Air Quality
Division to discuss permit application requirements early in the
application process. All information submitted to DEQ must be certified
by a responsible official to be true, accurate,
and complete.

| 15-Day Pre-Permit Construction
Approval Guidance |
The
15-Day Pre-Permit Construction Approval Guidance is available in
accordance with the Rules
for Control of Air Pollution in Idaho (IDAPA 58.01.01.213) (pdf
on Department of Administration Web site) only
for those sources that satisfy the following conditions:
- Have completed a comprehensive air quality assessment
and regulatory review,
- Are not proposing a new major facility or a
major modification,
- Are not utilizing emission offsets (netting),
and
- Are willing to commence construction at their
own risk prior to issuance of a PTC. A risk exists because the
owner or operator may not operate the source until a PTC is issued.
Thus, if a PTC is ultimately denied, or is issued but contains
limits unacceptable to the permittee, the permittee may simply
be out the money spent constructing an inoperable source.

| Fees |
| Both
an application fee and and a processing fee are required to obtain
a PTC.
Application Fee
An application fee of
$1,000 is required with any PTC application submitted to DEQ. DEQ
will not begin processing the application until the application
fee is received.
Processing Fee
A PTC
processing fee is assessed for each PTC that is issued, based on
any increase in air pollution emissions resulting from the permitted
project. DEQ calculates and assesses PTC processing fees according
to the following schedule (fugitive emissions are excluded): |

| Relocating Your Portable Equipment?
|
Don't forget
to submit a portable-equipment relocation notice at least 10 days
in advance of relocating portable equipment.

Equipment Relocation Form. |

| Air Modeling |
Air modeling
is required for certain permitting actions—including PTCs—to
demonstrate that all applicable ambient air quality standards will
be met if the proposed construction or facility modification is
completed or that an existing facility is complying with the the
standards.
A DEQ
guidance document has been developed to help air permit applicants
understand DEQ’s expectations for ambient air impact analysis
and prevent unnecessary delays in the permit process. The guideline
describes when modeling is required; explains applicable standards,
methodology, and analysis; and provides checklists and templates
for conducting modeling and reporting modeling results.

| Guidance for the Remediation
of Petroleum-Contaminated Media |
This guidance
addresses the air quality permitting/exemption requirements of IDAPA
58.01.01.222.03, as well as the state requirements of the Underground
and Leaking Underground Storage Tank program. Remediation projects
that do not meet the air pollution requirements of this guidance
must either self-exempt in accordance with the Rules
for the Control of Air Pollution in Idaho (IDAPA 58.01.01) or
obtain a PTC.
