A Cabarrus County legislator wants to give his county a defense against Charlotte's sewage sludge, which some of his constituents have rallied against in recent months.
Rep. Larry Pittman, a Concord Republican, is among the primary sponsors of the bill filed Tuesday. The bill lets counties that incinerate sludge -- that would be Cabarrus -- require that sludge be burned before it's spread as fertilizer on farm fields.
Counties without incinerators could force an "alternate method" of sludge treatment to reduce disease-carrying pathogens and rodents.
Charlotte Water's opponents in the Rowan-Cabarrus community of Gold Hill say they're more worried about heavy metals and toxic chemicals tainting soil and groundwater.
The utility this month withdrew an application to expand its sludge fields by 1,300 acres in Cabarrus, Rowan and Iredell counties. But its existing North Carolina permit expires March 31 and will have to be renewed, so could apparently be affected by the sludge bill.
Charlotte Water canceled the request after the state cited a Rowan County property that would have been included in the expansion for environmental violations.
Cabarrus County, meanwhile, cranked up a new, $20 million power plant fueled by sludge last October. The county landfills the ash that's left.
Cabarrus says it would welcome Charlotte's sludge, but the city has said incineration is not a viable alternative for economic and other reasons.
Pittman's Republican cosponsors are Rep. Carl Ford of Rowan County and Rep. Michael Speciale of Craven County. The bill now goes to the House Local Government committee, which Ford co-chairs, and if endorsed there to the Environment committee.

Duke scientists finds climate models inconsistent
A Duke University-led study questions the reliability of the climate models used to project short-term swings in temperature and the future extent of warming.
Patrick Brown, a Duke doctoral student in climatology, and two coauthors analyzed 34 models used by the Intergovernmental Panel on Climate Change in its most recent report, completed in November.
Most of the models probably underestimate how much surface temperatures change from decade to decade, says the study published last week in the Journal of Geophysical Research. The models also don't consistently explain why they vary, it says.
That means too much emphasis shouldn't be placed on recent temperature trends, the study warns.
"The inconsistencies we found among the models are a reality check showing we may not know as much as we thought we did," Brown said in a Duke release. He added that the findings don't mean the planet won't warm as greenhouse gases accumulate in the atmosphere.
"It just means the road to a warmer world may be bumpier and less predictable, with more decade-to-decade wiggles than expected.... Don't assume that the reduced rate of global warming over the last 10 years foreshadows what the climate will be like in 50 or 100 years."
Global surface temperatures rose quickly in the 1980s and 1990, but have stayed relatively stable since then.
The National Climatic Data Center in Asheville reported that surface temperatures in 2014 were the warmest since record-keeping began in 1880. Nine of the 10 warmest years in that 135-year span have occurred in this century.
Martin's coauthors were Wenhong Li of Duke's Nicholas School of the Environment and Shang-Ping Xie of the University of California San Diego.

Environmental Management Commission chair resigns
Benne Hutson, the Charlotte lawyer who led North Carolina's environmental rule-making board, has resigned under the weight of time spent on state business.
Sen. Thom Tillis was the N.C. House leader when he named Hutson, who practices environmental law, to the Environmental Management Commission in 2012. When the Republican-led legislature wiped the board clean the following year, Hutson was reappointed as chair.

"I can't commit the time to do the job and do it right," Hutson said. "I now have a real appreciation for the value of public service, and I have a much greater appreciation for the quality of the staff at DENR. They’re just really good."
His resignation, effective last Thursday, comes as the Department of Environment and Natural Resources also roils its top management. Gov. Pat McCrory this month named longtime staff member Donald van der Vaart to replace John Skvarla as environment secretary. Van der Vaart promptly replaced assistant secretaries Mitch Gillespie, who will move to a post in Asheville, and Brad Ives, who left DENR.
Under Hutson, the EMC undertook the business-friendly legislature's mandate to review environmental rules and delete those deemed unnecessary. Most of those reviewed so far, for surface water, wetlands and dry-cleaning businesses, are in the process of being readopted. But Hutson said commission members "really started raising questions" about whether proposed rules will work as intended.
The commission also lost a court case over its interpretation of state rules on contaminated groundwater, a key issue in regulating Duke Energy's coal ash ponds. A Wake County judge last year reversed the EMC, in part, by ruling that the state can require "immediate action" to stop the source of contamination. The case is before the state Supreme Court.
Hutson said he's spent time reaching out to skeptics of the Republican-dominated state government and tried to make the EMC's work transparent to the public.
"If everybody has a chance to have their say, we may have disagreements at the end but it's not nearly as strident as it would have been," he said.

Utilities panel keeps status quo on green-energy rates
North Carolina's Utilities Commission has opted not to change the way utilities calculate the rates they have to offer private developers for renewable energy.
Last week's order stabilizes, for now, the economic climate under which commercial solar farms are built. North Carolina ranks fourth nationally for solar capacity, the Solar Energy Industries Association says.
Utilities base the rates they pay for green energy on what are called avoided costs. In North Carolina's case, that's the cost of building gas-fired power plants to meet periods of peak demand for electricity.
Duke Energy says the "peaker" method results in its paying too much for solar power. Solar developers say it pays them too little. The commission took a middle ground, keeping the current method.
The order retained the threshold for standardized purchase contracts, which don't have to be individually negotiated, at 5 megawatts and smaller. Duke had argued that the threshold should be reduced to 100 kilowatts.
The commission also kept the maximum contract term at 15 years, turning aside green-energy arguments for longer contract terms and utility pleas for shorter ones.
"It looks like the status quo carried the day, which probably means it's going to be a good year for solar," said Duke spokesman Randy Wheeless. The state's renewable-energy tax credit, a powerful incentive behind solar's expansion, will expire Dec. 31 unless legislators renew it.
Said the North Carolina Sustainable Energy Association: "By making this finding and rejecting the monopoly power companies’ efforts to roll back the established policy, the commission itself recognized we’re better off with clean energy. North Carolina customers and the economy are the real winners under the commission's order."
The Utilities Commission is now taking comments on how to relieve a congested queue of proposed solar projects. Utilities say more than 700 proposals are now before them, many of which will never be built.

Chatham County opposes Duke's ash disposal
Chatham County commissioners cited "substantial health and environmental risks" this week in opposing Duke Energy's plan to dump coal ash into open-pit clay mines.
Commissioners adopted a resolution against Duke's plan, announced last month, to send 2.9 million tons of ash to mines in Chatham and Lee counties.
Lee County officials have said they want the county to be compensated for taking the waste, likening it to host fees typically paid for regional solid waste landfills.
The Chatham resolution says the plan would expose residents to risks from potentially toxic elements in ash. It identifies "shortcomings" in the legislation this year that ordered Duke to close its 32 ash ponds, including lack of local control over ash disposal and fees.
Duke has said it needs to move quickly to meet deadlines set out in the legislation. The initial phase of work would move ash from four power plants, including Riverbend west of Charlotte, starting early next year.
