The Operator Submission And Validation Environment (OSAVE) is a web-based application designed to assist pipeline operators with displaying and querying data related to:
- gas transmission and hazardous liquid pipelines,
- liquefied natural gas plants, and
- breakout tanks
under Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) jurisdiction for the purpose of reviewing pipeline data accuracy.
Pipeline operators are required by PHMSA to review their NPMS data annually for accuracy. OSAVE aids pipeline operators in the annual review process with tools, queries, and methods to notify NPMS staff that the data is still accurate or fulfill the yearly NPMS submission requirement in the event that changes have occurred. This application is not intended for anyone other than pipeline operators with data in the NPMS.
OSAVE is a password-protected application. Operators should use their PIMMA username and passwords to access OSAVE. Once logged in, the OPIDs to which the user has access are listed in a drop-down list. If an OPID is missing from the list in OSAVE, operators should email
firstname.lastname@example.org requesting that it be added to their PIMMA account. PIMMA login information for the purpose of using OSAVE cannot be shared among coworkers. No consultants/subcontractors may be issued a personal username and password. If a written confidentiality agreement exists between the operator and consultant/subcontractor stating that the login will only be used for the purposes of the project and will not be redistributed, the operator may opt to share his/her login with the consultant/subcontractor.
The operator may only review pipeline data that the company has previously submitted to the NPMS. If the company operates and submits pipeline data to the NPMS under more than one OPID, the operator may only review/submit data for one of the OPIDs during a single OSAVE session. The OPID that the data was submitted under must belong to the operating company and must be associated with the operator’s PIMMA account.
The OSAVE map viewer is intended to be used at any time throughout the year and allows operators to view the spatial location and attribute information of the OPID’s pipelines, LNG plants, and breakout tanks. However, OSAVE is geared specifically for pipelines, and the Data Summary tools only reflect the pipelines in the NPMS national layer for the corresponding OPID. The display of submission history reflects only the pipeline submissions. The submission-based workflows (e.g., notification of no changes, edits via a map viewer or additions to existing data in place of a traditional submission, traditional submissions replacing all existing data, and removal of all pipelines) are for pipeline data only. To review LNG plant or breakout tank data, operators may use either OSAVE or PIMMA, as both applications have the same functionality in regards to these data layers. If it has been identified that changes to the LNG plant and/or breakout tank data are needed, please make the appropriate LNG plant or breakout tank submission to NPMS staff. If it is determined that the LNG plant and/or breakout tank data is accurate as is and, therefore, needs no changes, please notify NPMS staff at
All information obtained and all maps produced from OSAVE are for official use only and must be treated as DOT proprietary information. Only NPMS staff has the right to redistribute maps or information from the NPMS.
