to hourly values prior to air quality 

modeling. This may be done with 

temporal profiles in several steps, such 

as annual-to-month, month-to-day, and 

day-to-hour. The exact method used 

depends on the type of emissions being 

processed. The EPA seeks comment on 

the allocation of the emission 

inventories to month, day, and hour for 

all types of emission processes. In 

particular, the EPA seeks information 

that could help improve the temporal 

allocation in 2017 of emissions from 

EGUs, nonroad mobile sources, 

residential wood combustion sources, 

and the temporal allocation of vehicle 

miles traveled needed to model onroad 

mobile sources. The EPA seeks localand region-specific data that can be 

used to improve the temporal allocation 

of emissions data. 

• Spatial surrogates. Spatial 

surrogates are used to allocate countylevel emissions to the grid cells used for 

air quality modeling. The EPA requests 

comment on the spatial surrogates used 

to spatially allocate the 2011 and 2017 

emissions. The same spatial surrogates 

are used in the base and future years. 

• Chemical speciation. Prior to air 

quality modeling, the pollutants in the 

emission inventories must be converted 

into the chemical species used by the air 

quality model using speciation profiles. 

The speciation profiles provided are 

consistent with version 4.4 of the 

SPECIATE database. The EPA requests 

comment on the provided speciation 

profiles, as well as any information that 

could help improve the speciation of oil 

and gas emissions in both the eastern 

and western U.S. in 2017. Oil and gas 

speciation information, along with VOC 

to TOG adjustment factors that are used 

to compute methane emissions, would 

be of the most use at the county or oil/ 

gas basin level of detail and also for 

each distinct process at oil and gas 

drilling/production facilities (e.g., glycol 

dehydrators). 

To aid in the interpretation of the 

provided data files and how they relate 

to the aspects of the data on which the 

EPA is requesting comment, the EPA 

has provided a summary document in 

the docket that describes in more detail 

the provided data and summary files.

Final 2014 Effluent Guidelines Program 

Plan and 2014 Annual Effluent 

Guidelines Review Report 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability. 

SUMMARY: This notice announces the 

availability of the Environmental 

Protection Agency’s (EPA) Final 2014 

Effluent Guidelines Program Plan and 

EPA’s 2014 Annual Effluent Guidelines 

Review Report. Section 304(m) of the 

Clean Water Act requires EPA to 

biennially publish a plan for new and 

revised effluent guidelines, after public 

notice and comment. The Plan identifies 

any new or existing industrial categories 

selected for effluent guidelines and 

provides a schedule. EPA typically 

publishes a preliminary plan upon 

which the public is invited to comment, 

and then publishes a final plan 

thereafter. EPA published the 

Preliminary 2014 Plan on September 16, 

2014, and received public comment on 

it.

SUPPLEMENTARY INFORMATION: 

I. General Information 

A. Supporting Documents—Key 

documents providing additional 

information about EPA’s 2014 annual 

review and the Final 2014 Plan include 

the 2014 Effluent Guidelines Review 

Report and the Final 2014 Effluent 

Guidelines Program Plan. 

B. How can I get copies of these 

documents and other related 

information?

II. How Is This Document Organized? 

The outline of this notice follows. 

A. Legal Authority 

B. Summary of the Final 2014 Effluent 

Guidelines Program Plan 

A. Legal Authority 

This notice is published under the 

authority of the CWA, 33 U.S.C. 1251, 

et seq., and in particular sections 301(d), 

304(b), 304(g), 304(m), 306, 307(b) and 

308 of the Act, 33 U.S.C. 1311(d), 

1314(b), 1314(g), 1314(m), 1316, 

1317(b), and 1318. 

B. Summary of the Final 2014 Effluent 

Guidelines Program Plan 

EPA prepared the Final 2014 Effluent 

Guidelines Program Plan (the Plan) 

pursuant to Clean Water Act section 

304(m). The Plan provides a summary of 

EPA’s review of effluent guidelines and 

pretreatment standards, consistent with 

CWA sections 301(d), 304(b), 304(g), 

304(m), and 307(b). It includes EPA’s 

evaluation of indirect discharge 

categories that do not have categorical 

pretreatment standards for the purpose 

of identifying potential new categories 

for which pretreatment standards under 

CWA section 307(b) might be warranted. 

From these reviews, the Plan identifies 

any new or existing industrial categories 

selected for effluent guidelines, and 

provides a schedule. In addition, the 

Plan presents any new or existing 

categories of industry selected for 

further review and analysis. The Final 

2014 Plan and the 2014 Annual Review 

Report can be found at http://
