  1. 2014 Electricity Forms Re-clearance Vlad Dorjets, Form EIA-860 Project Leader Environmental Equipment Data on Forms EIA-860 and EIA-923

  2. Context • Presentation address environmental equipment captured on Schedule 6 of Form EIA-860 and Schedule 8 of Form EIA-923 • Presentation excludes cosmetic changes, instruction clarifications, non-structural changes and other changes not requiring management deliberation to the Form EIA-860

  3. Structural Change: Collect Enviro. Data from All Applicable Plants ≥ 25 MW IMPORTANCE: MediumDIFFICULTY: Low ISSUE: Data on boilers, cooling systems, and stacks/flues is only collected from plants with of least 100 MW (other data collected for plants of at least 10 MW) so dropping threshold would increase coverage, make form consistent with most EPA regulations and provide valuable data for internal and external analysis. RECOMMENDATION: TBD

  4. Structural Change: Create New Schedule on EIA-860 for Matrix of Equipment / Pollutant IMPORTANCE: High DIFFICULTY: Low ISSUE: Current structure of environmental data is difficult for respondents to enter and for customers to use. Moreover, it does not easily support new regulations like MATS which require equipment with multiple benefits RECOMMENDATION: Create matrix with key equipment along one axis and key pollutants on another and continue to capture additional detail on subsequent schedules

  5. New Equipment / Pollutant Matrix

  6. Structural Change: Drop Strategy Questions from EIA-860 IMPORTANCE: Low DIFFICULTY: Low ISSUE: Respondents may not always know why certain environmental equipment is being installed (i.e. what regulation and/or whether to meet federal, state or local regulations) and extent of data’s use is unknown. Moreover, regulations are constantly changing so become dated in the form. RECOMMENDATION: Delete Schedule 6, Part B.

  7. Structural Change: Modify Strategy Questions from EIA-860 IMPORTANCE: Low DIFFICULTY: Low ISSUE: If strategy is needed, update questions to reflect current regulations (316B, MATS, CSAPR, CCR) and means of compliance (allowances, dispatch, equipment change, and fuel type change for air; screen, flow rate change, cooling tower, other for water) RECOMMENDATION: TBD

  8. Proposed Changes to Mercury Questions • Equipment being used to capture mercury would be included in new matrix on Form EIA-860 • Add question to EIA-923 on mercury content of purchased coal • Change instructions to EIA-923 on fly ash from units with dry FGD to “FGD and/or mercury sorbentbyproducts” • Change instructions to EIA-923 on fly ash from FBC to “fly ash and FGD and/or mercury sorbent byproducts from fluidized bed combustion (FBC) units” • Modify way that “unknown” mercury content of purchased fuel is captured on EIA-923 to avoid confusion (e.g. “UNK” or -99)

  9. Proposed Changes to Acid Gases • Equipment being used to capture acid gases would be included in new matrix on Form EIA-860 • Add new question on chlorine content of purchased coal to EIA-923

  10. Proposed Changes to NOx Questions • Equipment being used to capture NOx would be included in new matrix on Form EIA-860 • Add questions to EIA-860 to capture in-service dates of new SCRs or SNCRs • Add NOx removal efficiency of CT units at combined cycle plants

  11. Proposed Changes to EIA-860 Cooling System Questions • Add question to EIA-860 on secondary water source • Add question to EIA-860 on discharge location • Add question to EIA-860 on presence of “helper” tower • Modify question on EIA-860 on average height of cooling water intake and outlet to reflect “above sea level” • Delete redundant question from Schedule 6F of EIA-860 on source of cooling water since Schedule 2 asks for name of water source • Delete questions from EIA-860 on distance from shore of intake and outlet locations

  12. Proposed Changes to EIA-923 Cooling System Questions • Add questions on maximum monthly values (in addition to existing average monthly values) for diversion, withdrawal, discharge and consumption • In cases where more than one cooling system type is present at a plant, add question to capture percentage that each type is used per month • In cases where more than one cooling water source is present at a plant, add question to capture percentage that each source is used per month • Add questions for respondents to indicate appropriate unit of measurement for water flow data

  13. Proposed Changes to Other Questions • Add questions to EIA-860 on (i) available ash storage capabilities and (ii), if ash pond is present, whether it is lined • Modify instructions on EIA-923 to clarify what should and should not be included when reporting power consumed to operate an FGD • Add question to EIA-860 on “design steam conditions” at either boiler outlet or steam intake for coal plants

  14. Other Questions Recommended for Deletion from EIA-860 • Manufacturers of Boilers, Low NOx Controls, and FGD Units • Stack coordinates and corresponding datum

  15. Proposed Changes Recommended by Other “Groups” Not Included in Presentation • Capital and operating costs
