"Stack or chimney" means a flue, conduit or opening designed and constructed for the purpose of emitting air contaminants into the outdoor air.

"Standard conditions" means or shall be 70 degrees Fahrenheit and one atmosphere pressure (14.7 psia or 760 mm Hg).

7:27-6.2 Standard for the emission of particles

(a) No person shall cause, suffer, allow or permit particles as measured by the performance test principles set forth in section 3 of this subchapter to be emitted from any source operation, except as provided in subsection (b) of this section, through any stack or chimney into the outdoor air in excess of the maximum allowable emission rate as determined below:

MAXIMUM ALLOWABLE EMISSION RATE FOR PARTICLES

Instructions:

1. From columns 1 and 2 above, determine the allowable emission rate based upon the potential emission rate of particles from the source operation as measured by the performance test principles set forth in subsections 3(a) and 3(b) of this subchapter.

2. From columns 3 and 4 above, determine the allowable emission rate based upon the source gas emitted from the source operation. Whenever dilution gas is, for any purpose, added to the source gas from a source operation, the source gas emitted shall be considered to be the gas discharge rate prior to such dilution;

3. The greater of the two emission rates as determined from 1 and 2 above shall be the maximum allowable emission rate. For rates between any two consecutive values stated in columns 1 and 3, the corresponding allowable emission rates shall be as determined by interpolation.

(b) The provisions of subsection (a) of this section shall not apply to any glass manufacturing furnace. Such furnace(s) shall be subject to the following:

1. No person shall cause, suffer, allow or permit particles as measured by the performance test principles set forth in section 3(a) and (b) of this subchapter to be emitted from any glass manufacturing furnace through any stack or chimney into the outdoor air in excess of the maximum allowable emission rate, as determined from the equation below:

i. A = 5 + (.48 x W);

ii. A = maximum allowable emission rate (lbs. per hr.);

iii. W = process weight per hour (tons per hr.)

(c) The provisions of subsection (b) of this section and section 5 (b) of this subchapter shall not apply to any glass manufacturing furnace used for the production of lead glass.

(d) No person shall cause, suffer, allow or permit particles to be emitted from any stack or chimney into the outdoor air the shade or appearance of which is greater than 20 per cent opacity, exclusive of visible condensed water vapor.

(e) The provisions of subsection (d) of this section shall not apply to particles the shade or appearance of which is greater than 20 per cent opacity, exclusive of visible condensed water vapor, for a period of not longer than three minutes in any consecutive 30-minute period.

(f) If a paint spray operation meets the definition of a signigicant source operation under N.J.A.C. 7:27-8 or 22, as applicable, and the operation is constructed, reconstructed, installed, or modified on or after March 31, 1991, the operation shall, at a minimum, be served by particulate control apparatus.

7:27-6.3 Performance test principles

(a) For purposes of measuring emissions in accordance with the provisions of section 2(a) and (b) of this subchapter, particles shall be drawn by isokinetic procedures from the stack or chimney and the weight of the particles determined gravimetrically after removal of uncombined water.

(b) The measured emission weight shall be the combined weight of all particles collected and analyzed in accordance with the sampling and analytical procedures set forth in N.J.A.C. 7:27B-1.

(c) Opacity measurements shall be carried out in accordance with the procedures set forth in N.J.A.C. 7:27B-2.

7:27-6.4 Emission tests

(a) Any person responsible for the emission of particles from a source operation shall, when requested by the department, provide the facilities and necessary equipment for determining the opacity of emissions being discharged through a stack or chimney and shall conduct such opacity tests using methods approved by the department. Opacity test data shall be recorded in a permanent log at such time intervals as specified by the department and shall be maintained for a period of not less than one year and shall be available for review by the department.

(b) Any person responsible for the emission of particles from a source operation shall, upon request of the department, provide such sampling facilities and testing facilities exclusive of instrumentation and sensing devices as may be necessary for the department to determine the nature and quantity of particles being emitted from the source operation. During such testing by the department, the source operation shall be operated under normal, routine operating condition or under such other conditions within the capacity of the source operation as may be requested by the department. The facilities may be either permanent or temporary, at the discretion of the person responsible for their provision, and shall conform to all applicable laws and regulations concerning safe construction and safe practice.

7:27-6.5 Variances

(a) Whenever a person responsible for the emission of particles from a source operation believes that advances in the art of control for the kind and amount of particles emitted has not developed to a degree which would enable the requirements of section 2 of this subchapter to be attained, he may apply to the department for a variance, setting forth his reasons and justifications. The department may issue a variance from section 2(a), (b) and/or (d) of this subchapter and such variance shall be valid for a period not to exceed five years fro the data of issuance and may be renewed upon application to the department, setting forth reasons and justifications for its continuation. Variances issued under the provision of this section shall be conditional on the compliance with any requirements which the department deems to be necessary.

(b) The department may grant a variance from section 2(b) of this subchapter, if the person responsible for the operation of a glass furnace demonstrates, to the satisfaction of the department, that the process weight for the furnace continually consists of greater 25 per cent by weight cullet. Such variance:

1. Shall not be granted unless the applicant demonstrates compliance with all other requirements of this chapter, including but not limited to compliance with subchapter 13 (Ambient air quality standards) of this chapter, as well as any other requirements the department deems necessary;
