Water: Aircraft Drinking Water Rule

Aircraft Reporting and Compliance System (ARCS)

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

US EPA has developed the Aircraft Reporting and Compliance System (ARCS) to facilitate the reporting of aircraft public water system (PWS) data, pursuant to the Aircraft Drinking Water Rule (ADWR) [40 CFR Part 141 Subpart X]. ARCS is a centralized web-based data collection and management system that performs logic checks on data entered, and will calculate final results for accountability and regulatory oversight.

ATTENTION! Air carriers subject to the ADWR must report to US EPA the following required information through ARCS, unless an alternative reporting method has been approved:

By April 19, 2011, for existing aircraft PWSs, air carriers must report:

  • A complete inventory of aircraft PWS fleet (see User Guide);
  • The date the Operations and Maintenance plan was developed;
  • The date the Coliform Sampling plan was developed; and
  • The frequency for routine disinfection and flushing, and the corresponding routine total coliform sampling frequency.

By October 19, 2011, for existing aircraft PWSs, air carriers must:

  • Conduct routine disinfection and flushing, and the corresponding total coliform sampling;
  • Report all remaining ADWR requirements, such as routine disinfection and flushing date, routine total coliform sampling dates and results, and corrective actions (when applicable);
  • Incorporate aircraft PWS Sampling plan(s) into the aircraft water system Operations and Maintenance plan; and
  • Incorporate the Operations and Maintenance plan(s) into FAA- accepted air carrier Operation and Maintenance program.

How to submit data

To enter, transmit, and manage aircraft PWS data, air carriers and US EPA Regions must request a UserID and password by completing the following:

Access to ARCS (electronic process)

  • Go to http://iaspub.epa.gov/arcs from any web browser
  • Click on [Request User Account]
  • Specify your Role (i.e., Primary, Secondary, Laboratory, or US EPA Region)
  • As prompted, input your contact information and other relevant information

Note:

  • All air carriers and US EPA Regions must request a User Account via this new electronic process.
  • To batch load aircraft PWS data, air carriers must use the new MS Excel Spreadsheet (downloaded via ARCS) 

How to retrieve data

Coming in 2012 – For the general public, access to aircraft PWS data (e.g., violations).

Development: Aircraft Reporting and Compliance System (ARCS) 

US EPA is developing ACRS in two phases:

  • Phase I
    US EPA has completed development of Phase I of ARCS to enable air carriers to submit aircraft PWS fleet inventory data by the compliance date of April 19, 2011.  Access to ARCS requires authentication using an EPA-issued userID and password. ARCS currently consists of (1) a Microsoft ® Excel Spreadsheet, as the submittal media, for batch loading new aircraft PWS inventory data. It contains all data elements required for reporting inventory data and can be downloaded via ARCS; and (2) a web-based user interface application for modifying and managing reported and new data.
  • Phase II
    US EPA is currently developing Phase II of ARCS to enable air carriers to report aircraft PWS procedural and other related data. US EPA plans on completing the development of ARCS phase II by summer 2011.
    US EPA has developed a companion “ARCS User Manual” that includes detailed descriptions on formats, data elements, and instructions on how to use ARCS. The “ARCS User Manual”, along with other guides (e.g., “ARCS Quick Tips”) can be downloaded via ARCS under [HELP].
