Reporting Element Definitions for Form MMS-131

Performance Measures Data

Recordable Incidents: This value includes all company and contractor recordable injuries and illnesses using the Bureau of Labor Statistics (BLS) Record Keeping Guidelines for Occupational Injuries and Illnesses, September 1986 edition (or latest edition) from January 1 through December 31, for all employees that are assigned to the operator's OCS locations. It also includes restricted activity cases that are associated with no-days-away-from-work incidents. Transportation of personnel (e.g., helicopter, boat) injuries and illnesses incurred while supporting OCS activities should be included regardless of the occurrence location (e.g., shore base, OCS, transit). If transportation services are shared between OCS operators and others, only appropriate injuries and illnesses (i.e., those for which the operator is accountable) should be included with the operator's records. Office staff and management who are located onshore should not be included unless the company has an established process to include only the time they spend offshore and any associated offshore injury/illness.

Lost Time Incidents: This value is the number of operations employee (company and contractor) injuries and illnesses on the OCS for which there were lost workdays, as defined by BLS guidelines on the OSHA 200 log (or latest edition). It includes injuries and illnesses involving both days away from work and restricted duty situations.

Employee Hours Worked: This value is the number of actual hours worked during the calendar year on the OCS by those production, drilling, or construction operations employees (i.e., company and contractor employees) assigned to an operator's OCS locations. Transportation employee hours worked should include all time worked regardless of location (excluding office staff and management), but allocated among operators if the services are shared. Do not include hours for which the employee is off work or sleeping. Therefore, record 24 hours only in the unusual event that an employee works through a full day.

Production Operations: This includes those employees engaged in activities related to production, wireline, maintenance, associated transportation, and associated catering.

Drilling Operations: This includes those employees engaged in activities related to drilling, well workover/completion/service, plugging and abandonment, maintenance, associated transportation, associated catering, and diving.

Construction Operations: This includes those employees engaged in activities related to offshore construction, piping, platform structural modifications, major equipment additions, pipelines, major painting activities, platform installations and decommissioning, maintenance, associated transportation, associated catering, and diving assigned to the operator's OCS locations. These activities are usually directed by a construction inspector or supervisor and are larger projects, in most cases.

EPA NPDES Noncompliances: This value is the same number of noncompliances from OCS leases as reported to the EPA on an annual Discharge Monitoring Report (DMR). For companies that submit DMRs to EPA on a monthly basis, this value is the number of noncompliances from OCS leases in the calendar year being reported.

Number and Volume of Oil Spills < 1 Barrel:

Number of Spills: This value is the annual calendar-year total number of oil spills of less than 1 barrel from production, construction, and drilling-related operations on the OCS. It includes lessee spills and contractor spills directly involved in supporting lessee's operations. It also includes spills from (1) pipelines within the facility where the operator had/should have had containment and (2) pipeline company-owned pipelines, operated by the facility. It does not include sightings. It does not include shipping-related incidents such as non-lease-related shipping spills, does not include hazardous substance spills, and does not include NPDES-related spills or sheens.

Volume of Spills: This value is the total volume of spills of less than 1 barrel on the OCS as defined in this project.
