AZTEC — Four organizations hope to lease space at San Juan County Industrial Park.

The current tenant, PESCO, is moving its operations and plans to vacate the industrial park by May 31.

County Manager Mike Stark presented the proposals to the San Juan County Commission during its May 21 meeting in Aztec.

Stark said all four proposals would be compatible with each other’s operations.

“I’m actually quite pleased with the proposals to lease this facility,” Stark said.

Turning fly ash into concrete 

Two of the companies interested in locating at the San Juan County Industrial Park plan on taking fly ash from power plants and converting it into concrete products.

The companies are looking to lease a 45-acre tract with associated industrial buildings that currently house PESCO. The entire industrial park is 190 acres.

Stark said one of those two companies currently operates locally — Four Corners States Form Block and Southwest Aggregate. The other is a Canadian-based company known as SonoAsh.

Stark said both companies anticipate the projects will have at least a 40-year lifespan. Four Corners States Form Block and Southwest Aggregate plans to replace fly ash with hemp if it runs out of fly ash.

Stark said Four Corners States Form Block and Southwest Aggregate has provided a letter of credit and plans on an initial $10 million investment. It has proposed leasing the industrial park facility for $10,000 a month for 10 years. Stark said it could create 25 new jobs.

SonoAsh has a similar, but larger operation that would generate 100 jobs. SonoAsh is proposing investing $1 billion to start the facility.

However, SonoAsh proposed a $1 annual lease in exchange for improving the property and the company would like to see an initial $6 million investment from the state to fund the start of operation.

Stark said the county would like to work with SonoAsh and believes there is potential for two companies to convert fly ash at the industrial park.

A place to film

Film Four Corners has asked to lease 94 acres south of the industrial park’s entrance road for two to five years for filming. The county would receive a portion of the earned revenue.

Racing at the industrial park

Tiger Alley Racing has asked to lease less than 20 acres of land to build a drag strip and eventually a motorsports complex.

The nonprofit has proposed a long-term lease of $300 a month and would invest $200,000 to build the drag strip.
