National Emission Standards for Hazardous Air Pollutants for 
Polyether Polyols Production; Correction

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; correction.

-----------------------------------------------------------------------

SUMMARY: This document corrects errors in the preamble and regulatory 
text for the ``National Emission Standards for Hazardous Air Pollutants 
for Polyether Polyols Production'' which was published in the Federal 
Register on September 4, 1997.

FOR FURTHER INFORMATION CONTACT: Mr. David Svendsgaard; Organic 
Chemicals Group, Emission Standards Division (MD-13), U.S. 
Environmental Protection Agency, Research Triangle Park, North Carolina 
27711, telephone number (919) 541-2380.

SUPPLEMENTARY INFORMATION:

Corrections to the Preamble

    In proposed rule FR Doc. 97-22364, beginning on page 46804 in the 
issue of September 4, 1997, make the following correction in the 
Supplementary Information section. On page 46805 in the first column, 
replace the first and second paragraphs of the column with the 
following:
    ``The Basis and Purpose Document, which contains the rationale for 
the various components of the standard, is available in the docket and 
on the TTN. This document is entitled Hazardous Air Pollutant Emissions 
from the Production of Polyether Polyols--Basis and Purpose Document 
for Proposed Standards, May 1997, and has been assigned document number 
EPA-453/R-97-010a.
    Other materials related to this rulemaking are also available for 
review in the docket. Some of the technical memoranda have been 
compiled into a single document, the Supplementary Information Document 
(SID), to allow interested parties more convenient access to the 
information. The SID is entitled Hazardous Air Pollutant Emissions from 
the Production of Polyether Polyols-- Supplementary Information 
Document for Proposed Standards, May 1997, and has been assigned 
document number EPA-453/R-97-010c.''
    In the same proposed rule document, under Discussion of Major 
Issues, on page 46815 in the second column, replace the second sentence 
of the second paragraph with the following:
    ``The approach used for determining these emission factors is 
explained in Docket No. A-96-38, Item No. II-B-6.''

Corrections to the Regulatory Text

    In the same proposed rule document, in section 63.1423(b), on page 
46824 in the second column, replace the definition for Group 1 
wastewater stream with the following:
    ``Group 1 wastewater stream means a process wastewater stream at an 
existing or new affected source that meets the criteria for Group 1 
status in Sec. 63.132(c) of subpart G, with the exceptions listed in 
Sec. 63.1433(a)(10) for the purposes of this subpart (i.e., for organic 
HAP listed on Table 4 of this subpart only).''
    In the same proposed rule document, in section 63.1423(b), on page 
46826 in the first column, replace the definition for Wastewater with 
the following:
    ``Wastewater means water that: (1) Contains either (a) an annual 
average concentration of organic HAP listed in Table 4 of this subpart 
of at least 5 parts per million by weight and has an annual average 
flow rate of 0.02 liter per minute or greater or (b) an annual average 
concentration of organic HAP listed on Table 4 of this subpart of at 
least 10,000 parts per million by weight at any flow rate, and that (2) 
is discarded from a PMPU that is part of an affected source. Wastewater 
is process wastewater or maintenance wastewater.''
    In the same proposed rule document, under Process Vent Control 
Requirements, on page 46827 in the second column, replace section 
63.1425(d) with the following:
    ``Requirements for Nonepoxide Organic HAP Emissions From Catalyst 
Extraction. The owner or operator of an existing affected source where 
polyether polyol products are produced using epoxide compounds shall 
reduce emissions of nonepoxide organic HAP from the sum total of all 
process vents associated with catalyst extraction by an aggregated 90 
percent for each PMPU. The owner or operator of a new affected source 
where polyether polyol products are produced using epoxide compounds 
shall reduce emissions of nonepoxide organic HAP from the sum total of 
all process vents associated with catalyst extraction by an aggregated 
98 percent for each PMPU. A PMPU that does not use any nonepoxide 
organic HAP in catalyst extraction is exempt from the requirements of 
this paragraph.''
    In the same proposed rule document, under Wastewater Provisions, on 
page 46843 in the first and second columns, replace section 
63.1433(a)(2) with the following:
    ``When Secs. 63.132 through 63.149 of subpart G refer to table 9 or 
table 36 of subpart G, the owner or operator shall only consider 
organic HAP listed in table 9 or table 36 of subpart G that are also 
listed on table 4 of this subpart, for the purposes of this subpart. 
Owners and operators are exempt from all requirements in Secs. 63.132 
through 63.149 of subpart G that pertain solely and exclusively to 
organic HAP listed on table 8 of subpart G. In addition, when 
Secs. 63.132 through 63.149 of subpart G refer to List 1, List 2, and/
or List 3, as listed in table 36 of subpart G, the owner or operator 
shall only consider organic HAP contained in those lists that are also 
listed on table 4 of this subpart, for the purposes of this subpart.''
