Test Methods and Performance 
Specifications for Air Emission Sources; Correction 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Correcting amendments. 
SUMMARY : The Environmental Protection 
Agency (EPA) is correcting a final rule that was published in the Federal Register on October 7, 2020, and was 
effective on December 7, 2020. The final rule corrected and updated regulations for source testing of emissions. This correction does not change any final action taken by the EPA on October 7, 2020; this action corrects the amendatory instructions for Methods 4 and 5. 
DATES : The correction is effective on 
March 23, 2021. 
ADDRESSES : The EPA has established a 
docket for this action under Docket ID No. EPA–HQ–OAR–2018–0815. All documents in the docket are listed at http://www.regulations.gov. Although 
listed in the index, some information is not publicly available, e.g., confidential 
business information or other information whose disclosure is restricted by statute.

SUPPLEMENTARY INFORMATION : In the 
final rulemaking published in the Federal Register on October 7, 2020 (85 FR 63394), there were some inadvertent errors made to Methods 4 and 5 due to unclear or incorrect amendatory instruction. In this correction document, we are clarifying and correcting the amendatory instructions for ‘‘Appendix A–3 to part 60’’ to correct the inadvertent errors and incorporate the revisions from the final rulemaking. In Method 4, we are revising sections 
8.1.3.1, 8.1.3.2, and adding sections 8.1.3.2.1, 8.1.3.2.2, 8.1.3.2.3, 8.1.3.2.4, 8.1.3.3, and 8.1.3.4. We are also revising section 12.1.3. 
In Method 5, we are revising sections 
12.3, 12.11.1, 12.11.2, 16.1.1.4, and 16.2.3.3.

8.1.3.1 Leak Check of Metering System 
Shown in Figure 4–1. That portion of the sampling train from the pump to the orifice meter should be leak-checked prior to initial use and after each shipment. Leakage after the pump will result in less volume being recorded than is actually sampled. The following procedure is suggested (see Figure 5–2 of Method 5): Close the main valve on the meter box. Insert a one-hole rubber stopper with rubber tubing attached into the orifice exhaust pipe. Disconnect and vent the low side of the orifice manometer. Close off the low side orifice tap. Pressurize the system to 13 to 18 cm (5 to 7 in.) water column by blowing into the rubber tubing. Pinch off the tubing and observe the manometer for one minute. A loss of pressure on the manometer indicates a leak in the meter box; leaks, if present, must be corrected. 8.1.3.2 Pretest Leak Check. A pretest leak check of the sampling train is recommended, but not required. If the pretest leak check is 
conducted, the following procedure should be used. 8.1.3.2.1 After the sampling train has been assembled, turn on and set the filter and probe heating systems to the desired 
operating temperatures. Allow time for the temperatures to stabilize. 8.1.3.2.2 Leak- check the train by first plugging the inlet to the filter holder and pulling a 380 mm (15 in.) Hg vacuum. Then connect the probe to the train, and leak-check at approximately 25 mm (1 in.) Hg vacuum; alternatively, the probe may be leak-checked with the rest of the sampling train, in one step, at 380 mm (15 in.) Hg vacuum. Leakage rates in excess of 4 percent of the average sampling rate or 0.00057 m
3/min (0.020 cfm), whichever is 
less, are unacceptable. 8.1.3.2.3 Start the pump with the bypass valve fully open and the coarse adjust valve completely closed. Partially open the coarse adjust valve, and slowly close the bypass valve until the desired vacuum is reached. Do not reverse the direction of the bypass valve, as this will cause water to back up into the filter holder. If the desired vacuum is exceeded, either leak-check at this higher vacuum, or end the leak check and start over. 8.1.3.2.4 When the leak check is completed, first slowly remove the plug from the inlet to the probe, filter holder, and immediately turn off the vacuum pump. This prevents the water in the impingers from being forced backward into the filter holder and the silica gel from being entrained backward into the third impinger. 8.1.3.3 Leak Checks During Sample Run. If, during the sampling run, a component (e.g., filter assembly or impinger) change becomes necessary, a leak check shall be conducted immediately before the change is made. The leak check shall be done according to the procedure outlined in section 8.1.3.2, except that it shall be done at a vacuum equal to or greater than the maximum value recorded up to that point in the test. If the leakage rate is found to be no greater than 0.00057 m
3/ 
min (0.020 cfm) or 4 percent of the average sampling rate (whichever is less), the results are acceptable, and no correction will need to be applied to the total volume of dry gas metered; if, however, a higher leakage rate is obtained, either record the leakage rate and plan to correct the sample volume as shown in section 12.3 of Method 5, or void the sample run. 
Note: Immediately after component 
changes, leak checks are optional. If such leak checks are done, the procedure outlined in section 8.1.3.2 should be used. 
8.1.3.4 Post-Test Leak Check. A leak 
check of the sampling train is 
mandatory at the conclusion of each sampling run. The leak check shall be performed in accordance with the procedures outlined in section 8.1.3.2, except that it shall be conducted at a vacuum equal to or greater than the maximum value reached during the sampling run. If the leakage rate is found to be no greater than 0.00057 m

unless the leakage rate observed during any 
of the mandatory leak checks (i.e., the post- 
test leak check or leak checks conducted prior to component changes) exceeds L a. If L p 
or L iexceeds La, Equation 5–1 must be 
modified as follows: 
(a) Case I. No component changes 
made during sampling run. In this case, 
replace V min Equation 5–1 with the 
expression: (Vm¥ (Lp¥ La)q) 
(b) Case II. One or more component 
changes made during the sampling run. 
In this case, replace Vm in Equation 5– 1 by the expression:

rates (L ior L p) which exceed L a.

Implementation of Executive Order on 
Access to Affordable Life-Saving Medications; Final Rule; Delay of Effective Date 
AGENCY : Health Resources and Services 
Administration (HRSA), Department of Health and Human Services (HHS). 
ACTION : Final rule; delay of effective 
date. 
SUMMARY : This final rule implements a 
further delay until July 20, 2021, of the effective date of the rule entitled 
‘‘Implementation of Executive Order on Access to Affordable Life-saving Medications’’ published in the Federal Register on December 23, 2020. This 
rule was scheduled to take effect on March 22, 2021, after a delay from its original effective date of January 22, 2021. HHS is delaying the effective date of the rule to July 20, 2021, to ensure that implementation of the rule does not impede HHS’s and health centers’ 
immediate priority work, on a nationwide basis, of responding to and mitigating the spread of COVID–19, including ensuring widespread and equitable access to COVID–19 vaccines, and maintaining the delivery of comprehensive primary health services to medically underserved populations, while considering how to address administrative/implementation issues raised by commenters and further address comments regarding the impact of the rule. 
DATES : As of March 22, 2021, the 
effective date of the final rule published at 85 FR 83822 (December 23, 2020), which was delayed at 86 FR 7059 (January 26, 2021), is further delayed 
until July 20, 2021.

SUPPLEMENTARY INFORMATION : 
I. Public Participation 
On March 9, 2021, the Office of the 
Federal Register placed a HHS notice of proposed rulemaking (NPRM) on file for public inspection. This NPRM was published in the Federal Register on March 11, 2021, proposing to further delay, until July 20, 2021, the effective date of the rule entitled ‘‘Implementation of Executive Order on Access to Affordable Life-saving Medications’’ published in the Federal Register on December 23, 2020. The 
comment period closed on March 14, 2021, with HHS receiving 198 comments on the proposed delay.
