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 onroadmobile sources. The EPA seeks localand region-specific data that can be used to improve the temporal allocation of emissions data.

• Spatial surrogates. Spatialsurrogates 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.

**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.

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:// water.epa.gov/lawsregs/lawsguidance/ cwa/304m/index.cfm
