sources. The gases covered in ANSI/ 

ASME PTC 19.10–1981 are oxygen, 

carbon dioxide, carbon monoxide, 

nitrogen, sulfur dioxide, sulfur trioxide, 

nitric oxide, nitrogen dioxide, hydrogen 

sulfide, and hydrocarbons; however, the 

use in this rule is only applicable to 

oxygen and carbon dioxide. 

In the proposed rule, the EPA is 

incorporating by reference the VCS 

ASTM D7520–16, Standard Test Method 

for Determining the Opacity of a Plume 

in the Outdoor Ambient Atmosphere, as 

an acceptable alternative to EPA Method 

9 with the following caveats: 

• During the DCOT certification 

procedure outlined in Section 9.2 of 

ASTM D7520–16, the facility or the 

DCOT vendor must present the plumes 

in front of various backgrounds of color 

and contrast representing conditions 

anticipated during field use such as blue 

sky, trees, and mixed backgrounds 

(clouds or a sparse tree stand). 

• The facility must also have standard 

operating procedures in place including 

daily or other frequency quality checks 

to ensure the equipment is within 

manufacturing specifications as 

outlined in Section 8.1 of ASTM 

D7520–16. 

• The facility must follow the 

recordkeeping procedures outlined in 

40 CFR 63.10(b)(1) for the DCOT 

certification, compliance report, data 

sheets, and all raw unaltered JPEGs used 

for opacity and certification 

determination. 

• The facility or the DCOT vendor 

must have a minimum of four 

independent technology users apply the 

software to determine the visible 

opacity of the 300 certification plumes. 

For each set of 25 plumes, the user may 

not exceed 15-percent opacity of anyone 

reading and the average error must not 

exceed 7.5-percent opacity. 

• This approval does not provide or 

imply a certification or validation of any 

vendor’s hardware or software. The 

onus to maintain and verify the 

certification or training of the DCOT 

camera, software, and operator in 

accordance with ASTM D7520–16 is on 

the facility, DCOT operator, and DCOT 

vendor. This method describes 

procedures to determine the opacity of 

a plume, using digital imagery and 

associated hardware and software, 

where opacity is caused by PM emitted 

from a stationary point source in the 

outdoor ambient environment. The 

opacity of emissions is determined by 

the application of a DCOT that consists 

of a digital still camera, analysis 

software, and the output function’s 

content to obtain and interpret digital 

images to determine and report plume 

opacity. The ASTM D7520–16 

document is available from ASTM at

The EPA is finalizing the use of the 

guidance document, Fabric Filter Bag 

Leak Detection Guidance, EPA–454/R– 

98–015, Office of Air Quality Planning 

and Standards (OAQPS), U.S. 

Environmental Protection Agency, 

Research Triangle Park, North Carolina,

provides guidance on the use of 

triboelectric monitors as fabric filter bag 

leak detectors. The document includes 

fabric filter and monitoring system 

descriptions; guidance on monitor 

selection, installation, setup, 

adjustment, and operation; and quality 

assurance procedures. The document is

J. Executive Order 12898: Federal 

Actions To Address Environmental 

Justice in Minority Populations and 

Low-Income Populations 

The EPA believes that this action does 

not have disproportionately high and 

adverse human health or environmental 

effects on minority populations and 

indigenous peoples, as specified in 

Executive Order 12898 (59 FR 7629, 

February 16, 1994). The impacts of these 

proposed rules are to clarify current 

rules and, for new sources built after 

publication of this proposal, to ensure 

compliance via frequent testing, to meet 

a lower opacity limit for melt shop roof 

vents, to report baghouse emissions as a 

facility-wide total, and to meet all the 

proposed standards at all times, 

including periods of startup, shutdown, 

and malfunctions. The documentation 

for this decision is contained in section 

IV.E of this preamble and in a technical 

report, Analysis of Demographic Factors 

for Populations Living Near Electric Arc 

Furnace Facilities, located in the docket 

for this rule.

Clean Water Act Hazardous Substance 

Worst Case Discharge Planning 

Regulations; Extension of Comment 

Period 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Extension of comment period. 

SUMMARY: The Environmental Protection 

Agency (EPA or the Agency) is 

announcing an extension to the 

comment period for the proposed rule 

requiring an owner or operator of a 

facility to prepare and submit a plan for 

responding, to the maximum extent 

practicable, to a worst case discharge, 

and to a substantial threat of such a 

discharge, of a hazardous substance 

published in the Federal Register on 

March 28, 2022. EPA is proposing to 

require planning for worst case 

discharges of Clean Water Act (CWA) 

hazardous substances for onshore nontransportation-related facilities that 

could reasonably be expected to cause 

substantial harm to the environment by 

discharging CWA hazardous substances 

into or on the navigable waters, 

adjoining shorelines, or exclusive 

economic zone. The comment period is 

being extended to July 26, 2022.

SUPPLEMENTARY INFORMATION: This 

document extends the public comment 

period established in the Federal 

Register for 60 days (87 FR 17890). In 

that Federal Register notice, EPA 

proposed a rule requiring an owner or 

operator of a facility to prepare and 

submit a plan for responding, to the 

maximum extent practicable, to a worst 

case discharge, and to a substantial 

threat of such a discharge, of a 

hazardous substance published in the 

Federal Register on March 28, 2022. 

EPA is proposing to require planning for 

worst case discharges of CWA 

hazardous substances for onshore nontransportation-related facilities that 

could reasonably be expected to cause 

substantial harm to the environment by 

discharging CWA hazardous substances 

into or on the navigable waters, 

adjoining shorelines, or exclusive 

economic zone. EPA received requests 

from potential commenters to extend 

the comment period to allow greater 

time to comment. EPA is hereby 

extending the comment period, which 

was set to end on May 27, 2022, to July 

26, 2022. Please note that late comments 

on this rule making may not be 

considered. 

To submit comments or access the
