City should OK plans for quarry expansion

Compromise is an art — the required give-and-take can be difficult.

And nobody is going to be entirely happy when the object is to expand Makakilo Quarry, which is adjacent to the residential community of Kapolei. The two land uses are not easily compatible.

But when the need for building materials on a still-developing island and the efforts of quarry operator Grace Pacific Corp. to soften the impact are factored in, the case to approve the expansion is all but made.

Grace Pacific's permit application should get a thumbs-up from the city planning department before the issue moves to a Planning Commission hearing next month.

Consider the realities:

  • The quarry supplies nearly 70 percent of the aggregate used in paving O'ahu's roadways, harbors and airports, and it's almost out of the needed Grade A basalt at its current excavation.

  • An adjacent vein would extend mining another 25 years. The state Department of Transportation is testing ways to expand the use of recycled materials in aggregate, so it could last even longer.

  • Asphalt prices would skyrocket if rock had to be imported.

  • Grace Pacific has made some critical concessions — the revision of the plans is one reason the city's permit process has been held up. The company has agreed to relocate its processing facilities to Campbell Industrial Park, away from homes, and to change its mining plan to make the slope gentler and less visually jarring.

    Both of those concessions make sense and have helped to defuse some of the community opposition to the project. The Villages of Kapolei Community Association board of directors has rescinded its opposition, although many residents would prefer the quarry were elsewhere.

    But it's necessary and not easily relocated. Mines are located where the good-quality minerals are found, and Grace Pacific already has tested other locations.

    The city's job is to let the work continue, and see that the company meets its pledge to be good neighbors.
