ALBUQUERQUE, N.M. (AP) — The Latest on PNM's shareholder meeting (all times local):

12:50 p.m.

A resolution that would have required New Mexico's largest electric utility to prepare a report on how it plans to deal with coal ash waste from the San Juan Generating Station has failed.

The group PNM Shareholders for a Responsible Future worked to get the measure on the agenda for Tuesday's shareholders meeting. The group said it received enough support to allow the measure to be refiled next year.

Public Service Co. of New Mexico has argued that a separate report is unnecessary since it addresses coal ash in filings with the U.S. Securities and Exchange Commission.

While the utility contends it's not responsible for the waste once it's transported from the San Juan plant, some shareholders and environmentalists have concerns about future liabilities since decommissioning costs will be passed on to customers after the plant closes in 2022.

A group of shareholders wants the state's largest electric provider to prepare a report on how the investor-owned utility plans to deal with waste generated by its coal-fired power plant in northwestern New Mexico.

The shareholders say the San Juan Generating Station produced more than 1 million tons of coal ash in 2017. It's used to backfill the mine that feeds the plant, but they have concerns about future liabilities , citing contamination in other states.

U.S. coal plants generate about 100 million tons of ash annually. An Associated Press analysis of data released by utilities last year showed widespread evidence of groundwater contamination around coal plants nationwide.

Public Service Co. of New Mexico plans to shutter San Juan in 2022 and recoup the decommissioning costs from customers through rates.
