MEMORANDUM-PROPOSED DATA CATEGORY ASSIGNMENTS FOR S UBPART W

To: Docket EPA-HQ-OAR-2011-0028

From: Lisa Bacanskas, EPA/Climate Change

Date: January 26, 2012

Subject: Proposed data category assignments for data reporting elem ents in 40 CFR part 98,

subpart W.

In this memorandum, we show the proposed data category a ssignments for data reporting

elements in subpart W – Petroleum and Natural Gas Syste ms Source Category of Part 98 as

referenced in the Proposed Confidentiality Determinations and Corrections to the Petroleum and

Natural Gas Systems Source Category, and Amendments to Table A-7, of the Greenhouse Gas

Reporting Rule. Each data element was assigned to one of 11 data categori es for the direct

emitter source categories. The table below shows th e proposed data category assignments for the

data reporting elements. Please note that certain subpar t W data elements have already been

assigned to the inputs to emission equations data category. See the [Final] Change to the

Reporting Date for Certain Data Elements Required Under the Mandatory Repor ting of

Greenhouse Gases Rule, published on August 25, 2011 (76 FR 53057).

For descriptions of the 11 direct emitter data categories and the categorical confidentiality

determinations made for eight of these categories, see the preambles to the proposed and final

rulemakings: Proposed Confidentiality Determinations for Data Required Under the Mandatory

Greenhouse Gas Reporting Rule and Proposed Amendment to Special Rules Governi ng Certain

.2Appendix AData Category Assignments for Subpart WList of Proposed Data Category AssignmentsNote:In the May 26, 2011 Final CBI rule, the EPA issued categorical confidentiality determinations for 8 direct emittercategories. The table below identifies eleven directemitter data categories for subpart W and in the headingthe final categorical determinations for eight data categories. Two of the data categories “Unit/Process ‘Static’ Characteristics That are Not Inputs to Emission Equations” and “Unit/Process ‘Operating’ Characteristics Thatare Not Inputs to Emission Equations” do not have categorical confidentiality determinations, as these determinations are made on an element-by-element basis. Finally, the EPA is not making final determinations on dataelements assigned to the “Inputs to Emission Equations” data category as is noted in the preamble to this rule.Key:(I) = assigned to the Inputs to Emission Equations category in the May 26, 2011 Final Deferral RuleI = assigned in this proposal to the Inputs to EmissionEquations categoryE = assigned in this proposal to a category with a categorical determination of “emission data”C = assigned in this proposal to a category with a categorical determination of “not emission data and CBI”X = assigned in this proposal to a category with a categorical determination of “not emission data and not CBI”PC = assigned in this proposal to a category without a categorical determination and is proposed to be CBIPX = assigned in this proposal to a category without a categorical determination and is proposed to not to be CBICategorySubpartData ElementReportingSectionFacility andUnit IdentifierInformation(Emission Data)Inputs toEmissionEquationsEmissions(EmissionData)Unit/Process'Static'CharacteristicsThat are NotInputs toEmissionEquationsUnit/ProcessOperatingCharacteristicsThat are NotInputs toEmissionEquationsCalculationMethodology& Method.Tier(EmissionData)Test &CalibrationMethods(NotEmissionData AndNot CBI)Production/ThroughputData That areNot Inputs toEmissionEquations(Not EmissionData And AreCBI)Raw MaterialsConsumedThat are NotInputs toEmissionEquations(Not EmissionData And AreCBI)Data ElementsReported forPeriods ofMissing Datathat are NotInputs toEmissionEquations(Emission Data)ProcessSpecific &Vendor DataSubmitted inBAMMExtensionRequests(Not EmissionData And AreCBI)W -
