Section 270.303  Agency Determination of Completeness

a)         In order for an initial or renewal CAAPP application or an application for a significant modification to be deemed complete by the Agency, the application shall provide all of the information required in Subparts C and D of the Part applicable to the source for which the application is being submitted.

b)         The Agency shall provide notice to a CAAPP applicant as to whether a submitted CAAPP application is complete. Unless the Agency notifies the applicant of incompleteness within 60 days of receipt of the CAAPP application, the application shall be deemed complete. (See Section 39.5(5)(f) of the Act)

c)         Where an applicant is proposing in its CAAPP application that an activity at the source be treated as an insignificant activity,  the Agency will make its completeness determination in accordance with subsection (a) above.  If the Agency requests any additional information regarding the proposed insignificant activity, such information shall be provided in accordance with Section 270.305 of this Part.

Section 270.304  Effect of a Timely and Complete Application Submittal

a)         An owner or operator of a CAAPP source shall not be in violation of the requirement to have a CAAPP permit under Section 39.5 of the Act if such owner or operator has submitted a timely and complete CAAPP application, until the Agency takes final action on the CAAPP application except as provided in subsection (b) below.

Any applicant who fails to submit any relevant facts necessary to evaluate the subject source and its CAAPP application or who has submitted incorrect information in a CAAPP application shall, upon becoming aware of such failure or incorrect submittal, submit supplementary facts or correct information to the Agency. In addition, an applicant shall provide to the Agency additional information as necessary to address any requirements which become applicable to the source subsequent to the date the applicant submitted its complete CAAPP application but prior to release of the draft CAAPP permit. (See Section 39.5(5)(i) of the Act)

Section 270.307  Agency Action on CAAPP Applications

a)         In accordance with Section 39.5(10) of the Act, the Agency shall issue or deny the CAAPP permit within 18 months after the date of receipt of the complete CAAPP application, with the following exceptions,

1)         Permits for affected sources for acid deposition shall be issued or denied within 6 months after receipt of a complete application in accordance with Section 39.5(17) of the Act;

4)         The Agency or USEPA determines that the permit must be revised or revoked to assure compliance with the applicable requirements (See Section 39.5(16)(a)(iv) of the Act).

b)         Notice to reopen

1)         The Agency shall provide written notice to the owner or operator of the CAAPP source of its intent to reopen a CAAPP permit at least 30 days prior to the date the permit is to be reopened, except that the Agency may provide a shorter time period in the case of an emergency.

2)         The notice shall include the grounds for the reopening and revision, including the terms and conditions that the Agency proposes to change, delete or add to the permit, and the information relied upon to make such determination.  If the Agency deems it necessary, the notice shall include a request for the CAAPP source to update and resubmit those parts of the CAAPP permit application subject to the reopening within a reasonable time frame.

c)         Response

1)         The CAAPP source may submit to the Agency a written response to the notice to reopen and revise the CAAPP permit within 30 days after receipt of the Agency's notice.

2)         The response shall include the following, as applicable:

A)        Details as to immediate plans for compliance with applicable requirements, including a proposed compliance plan and schedule of compliance;

B)        Any explanation of the source's current failure to comply with applicable requirements;

C)        An explanation for and correction of any inaccurate statements made in the CAAPP application that were used to establish the emission standards, limitations, or other terms or conditions in the CAAPP permit; and

D)        An assessment of the Agency's proposed correction of any material mistake found in the CAAPP permit.

3)         If requested in the notice, the owner or operator of the CAAPP source shall submit to the Agency, within a reasonable time frame specified in the notice, a revised CAAPP application.

d)         Draft permit or statement

1)         Within 90 days after receipt of the source's response or revised CAAPP application, whichever is later, the Agency shall prepare a draft CAAPP permit and statement of basis in compliance with the requirements of Section 39.5(8) of the Act and 35 Ill. Adm. Code 252 or a statement that the CAAPP permit does not need to be reopened and revised.

2)         The Agency shall include in the draft CAAPP permit such conditions as the Agency determines are necessary to assure compliance with all applicable requirements and correct any material mistakes or inaccurate statements described in the notice.

3)         The Agency may, to the extent practicable, provide the owner or operator of the CAAPP source with a reasonable opportunity to review and comment on the draft CAAPP permit prior to public notice.

4)         The Agency shall give notice of the draft CAAPP permit to the public, the owner or operator of the CAAPP source and affected states in accordance with the requirements of Section 39.5(8) of the Act and 35 Ill. Adm. Code 252.

e)         The requirements of Section 39.5(9) of the Act and 35 Ill. Adm. Code 252 regarding USEPA notice and objection shall apply to this Subpart.

f)         The Agency shall reissue the CAAPP only if all the requirements of Section 39.5(10) of the Act have been met.

Section 270.504  Reopenings Initiated by USEPA

a)         If USEPA notifies the Agency and permittee that cause exists to modify a CAAPP permit, the Agency shall send to USEPA and the permittee a proposed determination of modification, with supporting information explaining the grounds for the proposed determination.  The proposed determination shall be in accordance with the record, the Clean Air Act, regulations promulgated thereunder, the Act, and regulations promulgated thereunder.  Such proposed determination shall not affect the permit or constitute a final permit action for purposes of the Act or the Administrative Review Law [625 ILCS 32]. (See Section 39.5(16)(a) of the Act)

b)         The proposed determination and supporting information shall be sent to USEPA and the permittee within 90 days after receipt of USEPA's notification or 180 days if USEPA has extended the period for response.

c)         If USEPA objects to the proposed determination within 90 days after receipt, the Agency shall, within 90 days after receipt of such objection, resolve the objection and modify the CAAPP permit in accordance with USEPA's objection, based upon the record, the Clean Air Act, regulations promulgated thereunder, the Act, and regulations promulgated thereunder.

d)         If USEPA does not object to the proposed determination within 90 days after receipt, the Agency shall, within seven days after receipt of USEPA's final approval or within seven days after expiration of the 90-day period, whichever is earlier, take final action in accordance with the Agency's proposed determination.
