Texas commission ready to issue air permit for second Navasota power project

The Texas Commission on Environmental Quality on Feb. 25 issued a notice that it intends to approve a Prevention of Significant Deterioration air permit for the gas-fired Clear Springs Energy Project of Navasota South Peakers Operating Co. II LLC.

The project site is in Guadalupe County, Texas. The company proposes to install three new natural gas-fired combustion turbine generators (CTGs). The CTGs will be the General Electric 7FA.04 (183 MW each) model, operating as peaking units in simple cycle. Fuel for the CTs is to be limited to pipeline-quality, sweet natural gas containing no more than 0.5 grain total sulfur per 100 dry standard cubic feet (dscf).

“Navasota South Peakers Operating Company II LLC. has demonstrated that this project meets all applicable rules, regulations and requirements of the Texas and Federal Clean Air Acts,” said the notice. “The proposed facilities and controls represent [best available control technology]. The modeling analysis indicates that the proposed project will not violate the [National Ambient Air Quality Standards], cause an exceedance of the increment, or have any adverse impacts on soils, vegetation, or Class I Areas. In addition, the modeling predicted no exceedance of ESLs at all receptors for non-criteria contaminants evaluated. The Executive Director of the TCEQ proposes a preliminary determination of issuance of this permit for Navasota South Peakers Operating Company II, LLC. to construct the Clear Springs Energy Center as proposed.”

Air permit to be issued to another Navasota project

The TCEQ on Feb. 10 had issued a notice saying that Navasota South Peakers Operating Co. I LLC is nearing air permits that would authorize construction of the Union Valley Energy Center at Nixon in Wilson County, Texas. The permits would authorize three natural gas-fired CTs that would operate in simple-cycle mode. The planned CTs are the General Electric 7FA.04 model. Fuel for the CTs would be limited to pipeline-quality, sweet natural gas containing no more than 0.5 grain total sulfur per 100 dry standard cubic feet (dscf).

Parent Navasota Energy has lately been permitting three of these projects, with the third being the Van Alstyne Energy Center, which is a 543-MW simple-cycle gas-fired project located in Grayson County, Texas.

Navasota Energy was launched in 2005 to develop power generation projects in Texas to meet the state’s growing energy needs. Its CEO is Frank Giacalone and its president is Dan Hudson, both of whom are veterans of the Texas power industry.
