Rule 20-502 - SAMPLING, TESTS, AND MEASUREMENTS

502.1

The Mayor may conduct, or cause to be conducted, or require an owner or operator to conduct, tests of emission of air pollutants from any source. The Mayor shall not require an owner or operator to conduct tests with unreasonable frequency.

502.2

Upon request by the Mayor, the person responsible for the source to be tested shall provide necessary holes in stacks or ducts and any other safe and proper sampling and testing facilities that may be necessary for proper determination of the emission of air pollutants. The Mayor may take or cause to be taken samples of fuel by any appropriate means in the quantities he or she feels are necessary.

502.3

Notwithstanding any other provision to the contrary in this subtitle, the Mayor may require or approve modifications to testing and measurement procedures and methods, calculation methods and performance specifications provided in this subtitle, to take into account the following:

(a) Specific conditions at the site or location;

(b) Latest available techniques;

(c) Good practices;

(d) Equivalency of the modified technique with the specified technique, in terms of results;

(e) Simplicity of the modified technique in terms of adequacy of the results in determining compliance or violation; and

(f) Other relevant factors.

502.4

The Mayor shall require the submission of reports on any tests he or she may require. The reports shall do the following:

(a) Be reasonably comprehensive;

(b) Contain all raw data obtained during the tests, including data on calibration of equipment;

(c) Contain reasonable data on various design and operating parameters of the source and associated equipment;

(d) Contain reasonable data on the quantities and properties of fuel raw materials consumed; and

(e) Contain results of the tests in terms that can be compared directly to emission and other appropriate limitations in this subtitle.

502.5

Tests for particulate matter emissions, nitrogen oxide emissions, and sulfur oxide emissions shall be undertaken in accordance with the appropriate methods in Appendix A to Part 60 of Title 40 CFR, revised as of July 1, 1982.

502.6

Testing of fuel oil shall be undertaken in accordance with the most current version of the following methods, as appropriate for the application:

(a) To obtain fuel samples:

(1) ASTM D 270, "Standard Method of Sampling Petroleum and Petroleum Products;"

(2) ASTM D 4057, "Practice for Manual Sampling of Petroleum and Petroleum Products;" or

(3) ASTM D 4177, "Standard Practice for Automatic Sampling of Petroleum and Petroleum Products;"

(b) To determine the fuel oil grade: ASTM D 396, "Standard Specification for Fuel Oils;"

(c) To determine the sulfur concentration of fuels:

(1) ASTM D 129, "Standard Test Method for Sulfur in Petroleum Products (General Bomb Method);"

(2) ASTM D 1266, "Standard Test Method for Sulfur in Petroleum Products (Lamp Method);"

(3) ASTM D 1552, "Standard Test Method for Sulfur in Petroleum Products (High-Temperature Method";

(4) ASTM D 2622, "Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-Ray Fluorescence Spectrometry;"

(5) ASTM D 4294, "Test Method for Sulfur in Petroleum and Petroleum Products by Energy Dispersive X-ray Fluorescence Spectrometry;" or

(6) ASTM D 5453, "Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence;" and

(d) Other methods developed or approved by the Department or the Administrator of the United States Environmental Protection Agency (EPA).

502.7

Visible emissions may be read by a qualified observer without the aid of any devices, by an observer with the aid of hand-held charts prepared on the principle of the Ringelmann Smoke Chart, or by other reasonable devices approved by the Mayor.

502.8

An observer may become qualified to take visible emission readings without the aid of any devices by being certified in accordance with the appropriate provisions of item 3, Qualifications and Testing of Method 9, Appendix A to Part 60 of Title 40 CFR, revised as of July 1, 1982. That certification shall be valid for a period of one (1) year.

502.9

Qualified observers shall take readings in accordance with the appropriate provisions of items 2.1 Position, and 2.3 Observations, of Method 9 referred to in § 502.8. Readings by the qualified observer shall be taken momentarily at approximate intervals of fifteen (15) seconds and shall be recorded to the nearest five percent (5%) opacity; each momentary observation recorded shall represent the opacity of the emissions during the fifteen (15) second interval.

502.10

Continuous monitoring and recording equipment for visible emissions shall meet the performance specifications in the appropriate provisions of Performance Specification 1 in Appendix B to Part 60 of Title 40 CFR, revised as of July 1, 1982, and shall be installed, calibrated, operated, and maintained in accordance with the appropriate provisions of items 3.4 Cycling Times, 3.5 Monitor Location, 3.7 Zero and Drift, and 3.8 Span, in Appendix P to Part 51 of Title 40 CFR revised as of July 1, 1982.

502.11

[Repealed]

502.12

[Repealed]

502.13

Stationary sources other than those specified in §§ 502.14 and 502.17 shall be tested in accordance with the provisions of this section.

502.14

Stationary sources of hazardous air pollutants shall be tested in accordance with the provisions of 40 CFR, Part 61.

502.15

Except for sources subject to the standards of performance as set forth in 40 CFR Part 60, the Mayor may grant waivers on a case-by-case basis from the requirements of § 502.13 if, based upon a technical evaluation of the past performance of similar source types, using similar control methods, the Mayor reasonably expects the new or modified source to perform in compliance with applicable standards of performance.

502.16

Tests for determining the Reid Vapor Pressure of gasoline and gasoline-oxygenate blends shall be undertaken in accordance with appropriate methods as set forth in 40 CFR Part 80, Appendix E.

502.17

Tests for emissions of volatile organic compounds shall be undertaken in accordance with the appropriate methods in Appendix 5-1 to this chapter.

502.18

For the purpose of determining compliance with Subsection 904.1, the oxygen content of gasoline shall be determined by:

(a) Using the sampling methodologies set forth at 40 CFR Part 80, Appendix D (July 1, 1999), relating to sampling procedures for fuel volatility, or other methods approved by EPA and the Mayor;

(b) Using American Society for Testing and Materials (ASTM) test method D-4815-89, or any method approved by EPA and the Mayor;

(c) Using the procedures for calculating the oxygen content of gasoline described in the EPA guidance document entitled "Guidelines for Oxygenated Gasoline Credit Programs and Guidelines on Establishment of Control Periods Under Section 211(m) of the Clean Air Act as Amended", 42 U.S.C. 7545(m), which was published in the Federal Register on October 20, 1992 (57 FR 47853), or other methods developed or approved by EPA and approved by the Mayor.
