IDELEMENTCODES/CRITERIALENGTHTYPEINFORMATION DESCRIPTIONCERS MINIMALLY REQUIRED FIELDS
1Facility ID Number13ANA facility identifier assigned by the local regulator supporting cross-linking of CERS and local data system records. Because CUPAs do not consistently apply the original regulatory definition of this field (2 AN county 3 AN jurisdiction 6 AN facility number), CERS accepts any alphanumeric string up to 13 characters. The original regulator goals of this field are fulfilled through the CERS ID and CERS System Field "FacilityRegulatorKey" (20.0084).False
1aCERS IDCal/EPA assigned, 8- or 9- digit ID assigned to a specific facility that never has leading zeroes (begins at 10000001). Cal/EPA does not anticipate using 9- digit CERS IDs until the year 2020 or beyond.9NA CERS ID is a Cal/EPA-assigned, 8- or 9- digit ID to uniquely identify a facility in CERS. The CERS ID should remain unchanged across different owners/operators of a facility.False
3Business Name 70ANFull legal name of business.True
103Business Site Address 70ANStreet address where facility is located. No post office box numbers are allowed. This information must provide a means to geographically locate the facility.

Once assigned to a tank, the tank number should never be changed.True
432aCERS Tank ID # 12ANThis CERS Generated Tank ID # will be a unique ID # assigned to each and every UST in CERS. The ID # will consist of the CERS ID for the facility followed by a unique 3-digit # separated by a "-".
