Three stations are from Nairobi, two from Meru, one in Kisumu, Vihiga, Laikipia, Kiambu and another one in Uasin Gishu.
ERC now wants the respective County Commissioners to withdraw the licenses of the said stations as they are operating against the law.
“The outlets found in violation were further required to pay penalties and taxes prescribed under the applicable tax laws before consideration for resumption of business,” ERC said on Wednesday in an advertisement on the dailies.
The fuel stations include D.K Sedani in Vihiga, Nguvu Service Station in Kisumu, Anointed Petrol Station and Rice Enterprise Limited both from Meru, Rumuruti Umoja Filling Station in Laikipia and Modern Service Station in Kiambu.
Others are Petkay Fuel Distributors, Minefield Filling Stations and Mwene Filling Station all from Nairobi.
The regulator says it carried out a total of 3,044 tests from January to April out of 1,574 petroleum outlets.
“From the tests carried out, 99.5 percent were found compliant. However, fifteen tests from ten sites were non-compliant,” ERC said.
Some of the stations were found selling diesel mixed with kerosene, selling kerosene which is contaminated with gasoline or offering sale of transit or export diesel.
This come as oil marketers continue to push for higher taxation of kerosene to reduce the cases of fuel adulteration especially diesel.
“The ERC is mandated under section 95 of the Energy Act 2006 to monitor petroleum products offered for sale in the local market with the aim of preventing motor fuel adulteration or dumping of export bound fuels,” the regulator stated.
