Environmental & Natural Hazards

Clean air, stable ground, and an inland location keep permitting simpler and operating risk lower in Rockdale.

Air Quality

Milam County is in attainment for every federal air quality standard. In ozone nonattainment areas, new and expanding plants face stricter permit review and must offset their emissions, which adds time and cost before construction starts.

Why it matters

In attainment areas, new sources go through standard permit review. In nonattainment areas, major sources need emission offsets and the lowest achievable emission rate.

Rockdale gives you Central Texas access without the nonattainment permit burden.

Seismic Activity

Rockdale sits in one of the lowest earthquake-hazard zones in the country. The nearest area of meaningful seismic hazard is the New Madrid zone, more than 500 miles away in the Mississippi Valley.

Severe Weather

Rockdale's location keeps it out of the worst of both coastal and northern weather.

Tropical storms

About 140 miles inland

Hurricanes and tropical storms weaken quickly over land. By the time they reach Rockdale, they've typically dropped to rain and wind, without the storm surge and hurricane-force winds that hit the coast.

Winter storms

Mild Central Texas winters

Snow and ice are rare and short-lived this far south, so winter weather seldom disrupts operations or shipping for more than a day or two.

Site Environmental Studies

The Rockdale Industrial Park has completed Phase I and Phase II environmental site assessments, a wetlands delineation, cultural resources and endangered species reviews, and a geotechnical study. All reports are available on request.
