H.3.a.2.c Sampling shall be completed prior to the opening of the machine door and activation of any Fugitive Control System.

H.3.a.3 The Perchloroethylene concentration in the Drum shall be determined by one of the following methods:

H.3.a.3.a A sampling port and valve shall be appropriately placed to draw a sample from the interior of the Drum or the lint filter housing. The sampling port shall be connected to a gas chromatograph by one-quarter (1/4-) inch, outside diameter, Teflon tubing. Any sampling pump shall have Teflon diaphragms. The gas chromatograph shall measure the concentrations of Perchloroethylene in accordance with ARB Method 422 (17 CCR, Section 94132, December 31, 1991) or NIOSH Method 1003 (NIOSH Manual of Analytical Methods, U.S. Department of Health and Human Services, August 15, 1987).
H.3.a.3.b A sampling port and valve shall be appropriately placed to draw a sample from the interior of the Drum or the lint filter housing. The sampling port shall be connected by one-quarter (1/4-) inch outside diameter Teflon tubing to a Tedlar bag. Any sampling pump shall have Teflon diaphragms. The concentration of Perchloroethylene in the air sampled shall be measured in accordance with ARB Method 422 (17 CCR, Section 94132, December 31, 1991) or NIOSH Method 1003 (NIOSH Manual if Analytical Methods, U.S. Department of Health and Human Services, August 15, 1987) within 24 hours of sampling. If an independent laboratory is contracted to perform the analysis of the samples, the chain of custody procedures contained in ARB Method 422 or NIOSH Method 1003 shall be followed.

H.3.b For a control device on the exhaust of a Drying Cabinet, sampling and analysis shall be conducted using ARB Method 422 (17 CCR, Section 94132, December 31, 1991) or NIOSH Method 1003 (NIOSH Manual of Analytical Methods, U.S. Department of Health and Human Services, August 15, 1987).
H.3.c An alternative test method deemed acceptable by the Air Pollution Control Officer or Executive Officer of the District and the Executive Officer of the Air Resources Board.

 H.4 All test plans and test results shall be made available to the District and the Executive Officer of the California Air Resource Board upon request.
I. WATER-REPELLING AND DIP TANK OPERATIONS
No person shall perform water-repelling or Dip Tank Operations, after the applicable date shown in column 8 of Table 1, unless all of the following requirements are met:

I.1 All Materials to be treated with Perchloroethylene water-repelling solutions shall be treated in a Closed-Loop Machine, a converted machine, or a dip tank.
I.2 For Dip Tank Operations:

I.2.a The dip tank shall be fitted with a cover that prevents the escape of Perchloroethylene vapors from the tank and shall remain covered at all times, except when Materials are placed in and removed from the dip tank or while the basket is moved into position for draining.
I.2.b After immersion, the Materials shall be drained within the covered dip tank until dripping ceases.
I.2.c All Materials removed from a dip tank shall be immediately placed into a Closed-Loop Machine or a converted machine for drying and not removed from the machine until the Materials are dry.

J. COMPLIANCE
A Facility shall comply with all provisions of this section as follows:

J.1 By the applicable dates of compliance specified in column 1 through column 8 of Table 1.
J.2 For compliance with subsection F.3 " Environmental Training Requirements", an alternative Date Of Compliance shall apply if the District determines that the initial course of an Environmental Training Program for Perchloroethylene Dry Cleaning operations is not Reasonably Available.

J.2.a For existing facilities in the District, if the initial course is not Reasonably Available within 12 months of the effective date of this control measure in the District, the alternative Date Of Compliance for subsection F.3 only shall be 6 months from the date the District determines that the initial course is Reasonably Available.
J.2.b For each New Facility in the District, if the initial course is not Reasonably Available within the period from three months prior to two months following commencement of operation, the alternative Date Of Compliance for subsection F.3 only shall be one month from the date the District determines that the initial course is Reasonably Available.
