Provisions for rate filings are divided into two levels of operation. NMPSC Rule 980 [17.13.980 NMAC] provides that sewer utilities shall file for rates in one of two formats. Sewer utilities having annual operating revenues averaging $500,000 or more over any consecutive three-year period must file the most comprehensive package, set forth in the Appendix to NMPSC Rule 930. Sewer utilities having annual operating revenues averaging less than $500,000 over any consecutive three-year period may file a simpler package, set forth in the Appendix to this Rule.
