    To read the consent order, visit heraldonline.com. The order lists incidents dating back to 2011 as cause for the new requirements and penalties. They include:

    • Feb. 11, 2011

    DHEC and Tega Cay Water Service enters into a consent order to settle discharge permit violations “for failure to properly operate and maintain in good working order” all systems in Tega Cay. The company previously failed to comply with effluent limits for total phosphorus, and for discharging untreated wastewater into state waters.

    As part of the plan, the company agrees to document all overflows and report them to DHEC within 24 hours, audit its system for specific areas and locations where overflows occurred and provide corrective actions to eliminate them. A report detailing reports of those audits is required. Included is a $60,000 civil penalty for the company.

    • March 31, 2011

    DHEC staff receives the corrective action plan required by consent order. Progress reports begin arriving every six months, as required.

    • Dec. 27, 2012

    DHEC receives a letter including a six-month report. The letter states system rehabilitation needs “had been identified, the necessary repairs completed and an enhanced maintenance program had been implemented.” The utility reports work is complete “resulting in the near elimination of the sewer system overflows.” Tega Cay Water Service requests that the consent order be closed. The request was denied.

    • January-July 2013

    The utility reports 16 overflows between Jan. 1, 2013, and July 31, 2013, as a result of “heavy and extended duration rainfall events.” In six of the overflows, untreated or partially treated wastewater discharges into Lake Wylie. The company then undertakes “additional measures” to identify and correct problems in response to those overflows.

    • Aug. 9, 2013

    DHEC staff receive a report with results of the corrective actions plan implemented Jan. 1 of that year. The letter states that as of July 31, 2013, problems in the system “that had been identified were corrected.”

    • Sept. 1, 2013

    Root blockage causes a manhole at 10040 Tepa Place to overflow. Untreated wastewater reaches Lake Wylie.

    • Sept. 3, 2013

    A cleanout at 4112 Marquesas Avenue releases untreated wastewater into a storm drain leading into Lake Wylie. The utility reports the cause as a blockage in the sewer main.

    • Oct. 1, 2013

    DHEC staff holds an enforcement conference with executives Rick Durham and Patrick Flynn of Tega Cay Water Service’s parent company, Utilities Inc., and their attorneys to discuss recent problems. The company indicates it recently began utilizing new equipment to locate blockages in the system. Discussions include a consent order including a schedule to implement corrective actions to prevent future overflows and the payment of a civil penalty.

    • Dec. 23, 2013

    The utility reports six spills caused by “excessive flows due to heavy rains.” The total amount released is more than 178,000 gallons. Spills come from manholes at 1007 Palmyra Drive, 2141 Manawa Lane and 2095 Diamond Head Circle. Wastewater treatment plants No. 2 and No. 3 release an estimated 85,000 gallons each. A lift station at Point Clear Drive releases 5,000 gallons.

    • Dec. 29, 2013

    The utility reports three spills, citing the same cause. An estimated 10,000 gallons spill at 1007 Palmyra Drive from a leak lasting almost nine hours. Another 800 gallons comes from 2141 Manawa Lane. A spill at wastewater treatment plant No. 3 releases less than 5,000 gallons in half an hour.

    • Jan. 2, 2014

    A manhole at 16106 Heron Drive releases wastewater into a cove of Lake Wylie. The cause given is “roots in the main.”

— The state environmental agency has given Tega Cay Water Service 30 days to find a temporary solution to repeated sewage spills into Lake Wylie, and two years to complete an “expedited capital improvement project.”

The state Department of Environmental Control this week also ordered the water service to pay a $136,000 penalty within 30 days. The fine cannot be paid from rate increases.

In an order filed released Monday, DHEC outlined a variety of needed improvements and set deadlines for when they are to be completed.

“The company has 30 days to get a temporary fix in place to stop the spills, and a two-year plan is required to complete an expedited capital improvement project,” said Mark Plowden, DHEC spokesperson.

The order states that past spills, like the six on Dec. 23 estimated at more than 178,000 gallons and three more on Dec. 29 estimated at more than 10,000 gallons, violated the state’s Pollution Control Act. Such violations can result in fines of up to $10,000 per day. By rule, those fines are a company cost and can’t be wrapped into rate increases.

Tom Oakley with the utility’s parent company, Utilities Inc., said the order is a “good thing” for laying out what both parties should expect.

“It clearly outlines the work that we will do and the schedule on which the repairs and improvements will be completed,” he said. “There is no work in the plan that wouldn’t have been done eventually as part of our ongoing maintenance and improvement program, so we are happy to move forward with the work.”

One disgruntled utility customer had a mixed reaction to the state’s sanctions.

“How is this going to affect us when it comes time for another rate increase?” asked Linda Stevenson of the Tega Cay Water Citizens Advisory Council, formed by customers who said they are fed up with Tega Cay Water Service. Stevenson said that rather than fining the company, DHEC should have ordered it to use the money to improve service.

“I’m very upset,” she said. “That fine of $136,000 could go a distance toward fixing the system.”

Stevenson said she is pleased with some aspects of DHEC’s order.

“The good thing is, the heat is on this company and not on the city,” she said.

“It is pressuring (the company) to do something about it. I personally have had it with this company. We get lip service from them and that’s all.”

Tega Cay Mayor George Sheppard, also a critic of the company, said the order is “a good start.”

However, like Stevenson, he takes issue with the fine.

“The problem I have with the fine is the City of Tega Cay doesn’t get it. It goes into the coffers of the state and is not returned to the citizens of Tega Cay,” he said.

Sheppard also points out that the company can request an extension on the deadlines, which he feels takes some bite out of the order.

Other than that, he’s on-board with DHEC’s action.

“It’s an aggressive remedy,” Sheppard said. “It has taken the Tega Cay citizens advisory group and the city council [to get action] but we are on this and we will continue to stay on it.”

What’s required

DHEC’s order gives Tega Cay Water Service five days to to submit a plan “detailing interim measures” to eliminate spills by creating capacity to handle the wastewater load. Those measures must be in place within 21 days of state approval.

The company has 30 days to submit engineering plans for improvements at three wastewater treatment plants, then 90 days to apply for permits and 90 more to begin construction. The work must be finished within 120 days of construction starting.

A customer service plan is required within 30 days. It must show how the company will “provide timely notice to the customers of the affected area” when any spill occurs, according to the order.

A complete sewer main rehabilitation must be complete within 12 months. A rehabilitation of the entire service system must be complete within 18 months.

Tega Cay Water Service must submit a summary of improvements made within 90 days, and every 90 days thereafter. The summaries must be updated every 30 days.

DHEC also said the company must immediately begin a “capacity audit,” including a financial plan, lift station inspection and maintenance schedules, a sewer inspection and cleaning program. The audit is supposed to cover everything from an organizational chart and an inventory of spare parts to a “fats, oils and grease control program.”

The utility has 240 days to comply.

Other requirements are holdovers from the previous order. The company has to submit public notices to DHEC of any spill of at least 5,000 gallons and collect hourly samples of overflows. The company also must test for ammonia, biochemical oxygen demand, total phosphorus, fecal coliform and dissolved oxygen. Records must be provided to the state within 15 days of an overflow.

The company has 24 hours to notify the state of a spill, and five days to provide written documentation.
