N.Y. Comp. Codes R. & Regs. tit. 6, § 219-2.7 – Continuous emission monitoring.

(a) Any person who owns or operates a facility subject to these requirements must install and operate, prior to operation of the facility and in accordance with manufacturer's instructions, instruments acceptable to the commissioner for continuously monitoring the following emission and operating parameters:
1. (1) opacity;
2. (2) sulfur dioxide;
3. (3) hydrogen chloride;
4. (4) nitrogen oxides;
5. (5) carbon monoxide;
6. (6) carbon dioxide;
7. (7) oxygen;
8. (8) temperature; and
9. (9) combustion index.
  Monitoring instruments for continuously measuring opacity and concentrations of sulfur dioxide, carbon dioxide, and oxygen will be subject to Performance Specifications 1 (opacity), 2 (SO₂ and NO_x) and 3 (O₂ and CO ₂) set forth in title 40 CFR part 60, Appendix B (see section 200.9 of this Title).
(b) The requirement for hydrogen chloride (HCl) monitoring may be waived upon a satisfactory demonstration by the applicant that HCl cannot be monitored reliably at the facility and provided that an alternative monitoring procedure acceptable to the commissioner is implemented. Final determination of reliability will be made by the commissioner. If hydrogen chloride monitors are not installed initially, the commissioner may require installation in the future should such monitoring subsequently be determined feasible and necessary.
(c) A report indicating continuous emission monitoring equipment locations, as well as specifications, and procedures for calibration, operation, maintenance, and data evaluation and reporting must be submitted to the commissioner at least 90 days prior to installation of such equipment. This report must be distributed as set forth in section 219-2.6(f) of this Subpart and must be approved by the commissioner prior to equipment installation.
(d) A file of the emission and operating parameter measurements required by this section and other operating parameters specified in paragraphs (1) through (5) of this subdivision, and any additional parameters required by the commissioner as a result of new technology or information, must be maintained. Each permittee for a source subject to this Subpart will, where applicable, following each calendar quarter, tabulate and summarize emission and operating parameter measurements, and the following operating parameters, recorded during the preceding three months. Such quarterly summaries must be submitted as set forth in section 219-2.6(f) of this Subpart within 30 days after the end of each calendar quarter in a format acceptable to the commissioner:
1. (1) steam temperature in degrees F, steam pressure in pounds per square inch absolute and steam flow in pounds per hour (hourly average);
2. (2) hourly auxiliary fuel use per furnace in gallons per hour for fuel oil and cubic feet per hour for gaseous fuel;
3. (3) for electrostatic precipitators:
  1. (i) current flow per field in amperes;
  2. (ii) applied voltage per field;
  3. (iii) sparking rate per field;
  4. (iv) hourly average temperature at both inlet and-outlet of the device in degrees F; and
  5. (v) frequency and duration of maintenance or cleaning periods when the precipitator is not fully operational;
4. (4) for fabric filters:
  1. (i) hourly average pressure drop across each module and also across the inlet and outlet of the entire device in inches of water;
  2. (ii) number of compartments in use, hourly;
  3. (iii) hourly average temperature at both inlet and outlet of the device in degrees F; and
  4. (iv) frequency and duration of maintenance or cleaning periods when the fabric filter is not fully operational;
5. (5) for gaseous contaminant emission control devices:
  1. (i) hourly average pressure drop across device in inches of water;
  2. (ii) hourly average temperature at both inlet and outlet of the device in degrees F;
  3. (iii) reagent chemicals used in pounds per hour by chemical;
  4. (iv) water use in gallons per hour; and
  5. (v) frequency, duration, and description of periods when the device is not fully operational.
(e) Records and summaries of all measurements and operating parameters must be retained for at least three years, and made available upon request of the commissioner or his representative within 10 working days from receipt of the request.
(f) The quarterly summary of emissions and operating parameters required by this section will be forwarded to the department and other agencies identified in section 219-2.6(f) of this Subpart within 30 days of the end of each calendar quarter.
(g) Excess emissions and/or out of compliance operating parameters must be reported to the appropriate regional air pollution control engineer within one working day of occurrence, along with a program for immediate correction of these conditions.
(h) All reports required by this Subpart must include a section on data quality control and quality assurance. A plan for data quality control and quality assurance must be submitted 90 days prior to application for any certificate to operate and approved by the commissioner prior to issuance of the certificate to operate pursuant to Part 201 of this Title.
