By Matt Patterson Staff Writer mpatterson@oklahoman.comA systemwide review of Oklahoma Natural Gas pipelines in the wake of a Jan. 2 explosion that damaged or destroyed dozens of homes in a northwest Oklahoma City neighborhood has identified more than 200 other sections of potentially dangerous pipeline. The utility, which serves about 860,000 customers statewide, is in the midst of making needed repairs, but declined requests by The Oklahoman to identify the problem locations. “For security reasons, we do not disclose specifics regarding our gas pipe infrastructure,” ONG spokeswoman Cherokee Ballard said in an email. The Oklahoma Corporation Commission ordered the review following the January blast, which destroyed a home at 12505 Whispering Hollow Drive and sent its occupant to the hospital with severe burns.
