National Emission Standards for 

Hazardous Air Pollutants for the 

Portland Cement Manufacturing 

Industry and Standards of 

Performance for Portland Cement 

Plants; Correction 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule; correcting 

amendments. 

SUMMARY: The Environmental Protection 

Agency (EPA) published a final rule in 

the Federal Register on July 27, 2015, 

titled National Emission Standards for 

Hazardous Air Pollutants for the 

Portland Cement Manufacturing 

Industry and Standards of Performance 

for Portland Cement Plants. This final 

rule makes technical corrections and 

clarifications to the regulations 

published in that final rule. The rule 

also includes a provision describing 

performance testing requirements when 

a source demonstrates compliance with 

the hydrochloric acid (HCl) emissions 

standard using a continuous emissions 

monitoring system (CEMS) for sulfur 

dioxide measurement and reporting. 

DATES: Effective September 9, 2015.

SUPPLEMENTARY INFORMATION: 

Summary of Technical Corrections 

The EPA received communications 

from representatives of the Portland 

cement industry on five occasions in 

August 2015 (see memo to the docket 

(EPA–HQ–OAR–2011–0817) titled, 

‘‘Communications on Errors PCA 

August 2015’’). These communications 

outlined several errors in the regulatory 

text of the final rule (80 FR 44772). 

These all pertain to monitoring 

requirements. The EPA agrees that these 

are errors (typographical and 

unintended phrasing or omissions), and 

is correcting these errors in this 

document. We are also removing two 

passages (which consisted of four 

sentences) that were inadvertently left 

in the final amendments, but were 

discussed by the EPA as being removed 

in the Response to Comment (RTC) 

document for the final amendments (see 

docket item EPA–HQ–OAR–2011–0817– 

0870, page 8). In the RTC, we discussed 

that data substitution is not an allowed 

practice when determining compliance, 

but these four sentences discuss 

procedures for data substitution. 

Leaving these sentences in the rule, 

thus, does not reflect the EPA’s stated 

intention, and would lead to confusion 

given the direct conflict between the 

RTC document and the rule text. 

We are making one further technical 

correction involving timing of 

performance tests. The correction keeps 

in place the specified time by which 

performance tests must be conducted, 

but will no longer set out a window of 

time in which the test must be 

conducted. The net effect is that 

performance tests can be conducted 

earlier than the window of time in the 

current rule text if a source desires to 

conduct its performance test earlier. The 

EPA had already indicated in the RTC 

document that it was making this 

change (see docket item EPA–HQ–OAR– 

2011–0817–0870, page 5). The EPA 

regards this amendment as a 

clarification (the current rule could be 

interpreted to allow earlier testing) so 

that the rule reads precisely as intended, 

as stated by the EPA in the RTC 

document.

(c) * * * Performance tests required 

every 30 months must be completed no 

more than 31 calendar months after the

that specific pollutant is monitored 

using CEMS; performance tests required 

every 12 months must be completed no 

more than 13 calendar months after the 

previous performance test.

■ 3. Amend § 63.1350 by: 

■ a. In paragraph (k)(2)(ii), revising the 

last sentence. 

■ b. Revising paragraph (k)(2)(iii). 

■ c. In paragraph (l)(1) introductory text, 

revising the last sentence. 

■ d. In paragraph (l)(1)(ii)(B), revising 

the last sentence. 

■ e. In paragraph (l)(1)(ii)(C), removing 

the last two sentences. 

The revisions read as follows: 

§ 63.1350 Monitoring requirements. 

* * * * * 

(k) * * * 

(2) * * * 

(ii) * * * In this manner all hourly 

average values exceeding the span value 

measured by the Hg CEMS during the 

week following the above span linearity 

challenge when the CEMS response 

exceeds +/¥20 percent of the certified 

value of the reference gas must be 

normalized using Equation 22. 

(iii) Quality assure any data above the 

span value established in paragraph 

(k)(1) of this section using the following 

procedure. Any time two consecutive 

one-hour average measured 

concentrations of Hg exceeds the span 

value you must, within 24 hours before 

or after, introduce a higher, ‘‘above 

span’’ Hg reference gas standard to the 

Hg CEMS. The ‘‘above span’’ reference 

gas must meet the requirements of PS 

12A, Section 7.1, must target a 

concentration level between 50 and 150 

percent of the highest expected hourly 

concentration measured during the 

period of measurements above span, 

and must be introduced at the probe. 

While this target represents a desired 

concentration range that is not always 

achievable in practice, it is expected 

that the intent to meet this range is 

demonstrated by the value of the 

reference gas. Expected values may 

include ‘‘above span’’ calibrations done 

before or after the above span 

measurement period. Record and report 

the results of this procedure as you 

would for a daily calibration. The 

‘‘above span’’ calibration is successful if 

the value measured by the Hg CEMS is 

within 20 percent of the certified value 

of the reference gas. If the value 

measured by the Hg CEMS exceeds 20 

percent of the certified value of the 

reference gas, then you must normalize 

the one-hour average stack gas values 

measured above the span during the 24- 

hour period preceding or following the 

‘‘above span’’ calibration for reporting 

based on the Hg CEMS response to the 

reference gas as shown in equation 22 

below. Only one ‘‘above span’’ 

calibration is needed per 24 hour 

period. 

* * * * * 

(l) * * * 

(1) * * * The span value and 

calibration requirements in paragraphs 

(l)(1)(i) and (ii) of this section apply to 

HCl CEMS other than those installed 

and certified under PS 15. 

* * * * * 

(ii) * * * 

(B) * * * Any HCl CEMS above span 

linearity challenge response exceeding 

+/¥20 percent of the certified value of 

the reference gas requires that all above 

span hourly averages during the week 

following the above span linearity 

challenge must be normalized using 

Equation 23.

Tetraethylene Glycol; Exemption From 

the Requirement of a Tolerance 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This regulation establishes an 

exemption from the requirement of a 

tolerance for residues of tetraethylene 

glycol (CAS Reg. No. 112–60–7) when 

used as an inert ingredient (solvent) in 

pesticide formulations applied to 

growing crops. Exponent, Inc. on behalf 

of Drexel Chemical Company submitted 

a petition to EPA under the Federal 

Food, Drug, and Cosmetic Act (FFDCA), 

requesting establishment of an 

exemption from the requirement of a 

tolerance. This regulation eliminates the 

need to establish a maximum 

permissible level for residues of 

tetraethylene glycol. 

DATES: This regulation is effective 

September 11, 2015. Objections and 

requests for hearings must be received 

on or before November 10, 2015, and 

must be filed in accordance with the 

instructions provided in 40 CFR part 

178 (see also Unit I.C. of the 

SUPPLEMENTARY INFORMATION).
