N.J. Admin. Code § 7:27-8.18

Current through Register Vol. 56, No. 21, November 4, 2024

Section 7:27-8.18 - Permit revisions

(a) The following actions require prior approval from the Department through a permit revision:

1. A request for an increase in a maximum allowable emission limit, including correction of a typographical error or inaccurate calculation, if the correction would result in a higher maximum allowable emission limit;

2. An action that shall:

i. Increase actual emissions, to a rate or concentration greater than a maximum allowable emission limit; or

ii. Cause the emission of a new air contaminant not specified in the permit and certificate. If the permit and certificate allows emission of a group of air contaminants, such as "total VOCs," or "total particulates," then any non-HAP air contaminant in that group is considered to be specified in the permit and certificate;

3. Use of a new raw material not specified in the permit, if the use would cause any of the following results (if the use would not cause any of these results, it shall be processed as a seven-day-notice pursuant to N.J.A.C. 7:27-8.20, or as an amendment pursuant to N.J.A.C. 7:27-8.21):

i. An increase in actual emissions, to a rate or concentration greater than a maximum allowable emission limit;

ii. Emission of a new air contaminant not specified in the permit and certificate, at a level that meets or exceeds the applicable reporting threshold at N.J.A.C. 7:27-8Appendix 1, Table A, incorporated herein by reference, or at 17.9, Tables 3A and 3B; or

iii. The source to become subject to a requirement that did not previously apply;

4. A reconstruction, as described at N.J.A.C. 7:27-8.23, unless the reconstructed source has the potential to emit each of the air contaminants listed at N.J.A.C. 7:27-8Appendix 1, Table A, incorporated herein by reference, and at 17.9, Tables 3A and 3B, in amounts less than the applicable SOTA threshold level; in that case, the owner or operator of the source shall notify the Department of the reconstruction using the amendment procedures set forth at N.J.A.C. 7:27-8.21;

5. Any of the following changes, if the change would cause the ground level concentration of an air contaminant to increase in that portion of the atmosphere, external to buildings, to which the general public has access;

i. The replacement of an existing stack or chimney with a shorter stack or chimney;

ii. A change in the number of stacks or chimneys serving a source, which results in any discharge height less than that of the tallest stack or chimney existing prior to the change;

iii. An increase in the diameter of a stack or chimney; or

iv. A decrease in the exit temperature or volume of gas emitted from a stack or chimney;

6. Except as allowed at 7:27-8.21(b)6, the replacement of an entire permitted significant source with a replacement source. For the purposes of this section, replacement means that the replacement source will take the place of the replaced source in the manufacturing process, and the replaced source will be permanently shut down; or

7. Construction or installation of a new significant source (including a control apparatus), if there are existing, permitted sources onsite, and the new source could, under 7:27-8.4(h), be combined on one permit application with the existing permitted sources. If the new source could not be combined under one permit with existing permitted sources under 7:27-8.4(h), installation of the new source would require a new permit of its own.

(b) To obtain Department approval of a permit revision, the applicant shall demonstrate that the source shall meet the requirements of 7:27-8.11, Standards for issuing permits.
