background
Background
  • Currently the Air Force has active duty facilities in 31 states, with 13 of the 31 having multiple facilities
  • APIMS is in use at 50 of 62 CONUS Air Force bases
  • APIMS is also in use at 10 Army, 1 Marine and 2 Navy facilities

Background
  • Overwhelming majority of APIMS users have some form of an annual emission inventory requirement
  • 62 CONUS facilities meet this requirement in ≈ 50 different formats which leads to substantial costs
  • These factors have led to the current study

study goals
Study Goals
  • Develop a universal schema for submission of emission inventories
    • Working with partner States to ensure that the schema can be used by industrial and military facilities
  • Utilize all available technologies to maximize cost savings for all participants
    • Exploit the current Exchange Network Technologies and Services (i.e. Node Architecture, Schematron, Web Services, etc.)

I n t e g r i t y - S e r v i c e - E x c e l l e n c e

study goals1
Study Goals
  • Establish the Air Force node on the Exchange Network
    • Allows data flow from Air Force through CDX and to the appropriate State & Local agencies
  • Replace current AEI submission formats with electronic submission via the CDX using the Universal Schema for all APIMS users in the participating States.

study participants
Study Participants
  • Air Force / APIMS PMO
    • Total of 15 facilities using APIMS spread across the participating States
  • Nebraska
  • North Carolina
  • Texas
  • Utah
  • Washington
  • Maine
  • OAQPS providing guidance and facilitation

progress to date
Progress To Date
  • Universal Schema has been developed
    • Reviewed by participating States and the APIMS PMO to ensure that the States’ needs, as well as the Air Force needs, were addressed
    • Developed according to the data model structure of the Facility and Point Inventory Schema (EIS)
    • Utilizes a hierarchical, integrated structure instead of individual data element submissions

universal schema details
Universal Schema Details
  • Comprised of 9 “collections” of data
    • Facility/Site
    • Emission Unit
    • Emission Release Point
    • Emission Process
    • Operating Parameters
    • Emissions
    • Control Measures
    • Applicable Regulations

I n t e g r i t y - S e r v i c e - E x c e l l e n c e

universal schema details1
Universal Schema Details
  • Integrated the Exchange Network Shared Schema Components (SSC) into the Universal Schema
  • Hierarchical Structure – Eliminates data redundancy
  • Strict Data Validation – Results in cleaner data
  • Flexible Architecture implemented to allow differences in the number of elements that an entity desires to submit (i.e. Sites, Control Measures)
  • Built so that Data Lengths, and even Data Types, can be modified relatively easily
  • Designed and built to be Universal (Industry or Military)

remaining study milestones
Remaining Study Milestones
  • Create a Memorandum of Understanding (MOU) with all study partners
    • Initial draft created in May 2006
    • Finalized before data is passed from APIMS to the respective partner
  • Create a Schematron process against the universal schema
    • Will be reviewed and modified as needed during the schema testing process

14

remaining study milestones1
Remaining Study Milestones
  • Develop Flow Configuration Document
    • Will serve as the road map for data exchange between the Air Force and all participating partners
  • Universal Schema Testing
    • Verify export from APIMS in universal schema format
    • Verify transfer from Air Force Node to each State node
    • Investigate options for electronic signature

15

remaining study milestones2
Remaining Study Milestones
  • State review of submission package
    • Completed in parallel with universal schema testing
    • Review package to ensure all needed data is included
  • Develop converters for each State
    • Converters will allow transformation of data from the universal schema to an easier format for review

16

remaining study milestones3
Remaining Study Milestones
  • Move data exchange into full production
    • Dependent on successful completion of each previous milestone
  • Eliminate previous AEI Submission procedures
    • Dependent on verification of successful AEI submission via the CDX using the Universal Schema
