Mason County • I-3 Zoning

Real-World Impacts: Other I-3 Industries vs. Data Centers

The I-3 rules already cover high-impact uses like quarries, paper mills, chemical plants, and trucking terminals. If those standards work for heavier industries, why would a quieter, cleaner data center face tougher rules?

Noise

Use	Typical Sources	Relative Level	Plain-English Notes
Quarry / Mining	Blasting, crushers, loaders, haul trucks	High	Intermittent blasts and heavy machinery — loudest of I-3 uses.
Paper Mill	Fans, conveyors, drying equipment	High	Large fans and steam systems create continuous industrial noise.
Truck Freight Terminal	Idling, loading, alarms	Medium	Peaks at shift changes; diesel engines and brakes dominate.
Chemicals / Petroleum	Compressors, pumps	Medium	Constant motor/pump noise; occasional venting sounds.
Data Center	Cooling fans, backup-gen tests	Low	Steady hum; typically below community limits at boundary with screening.

Best practice: enforce noise limits at the property line, not oversized setbacks.

Dust / Particulates

Use	Main Sources	Relative Level	Plain-English Notes
Quarry / Mining	Blasting, crushing, unpaved haul roads	High	Significant dust without strict controls; requires watering, paving, enclosures.
Paper Mill (wood handling)	Chip handling, fiber dust	Medium	Managed with collection and housekeeping; still noticeable near operations.
Truck Freight Terminal	Yard movements on gravel, brake/tire dust	Medium	Moderate dust depending on surfacing and traffic volume.
Chemicals / Petroleum	Generally enclosed processes	Low	Particulates are typically minimal; main risks are process-related (see Fire).
Data Center	None (no bulk handling)	Low	No quarrying, stockpiles, or traffic yards; interiors require clean air.

Dust is best handled by site surfacing, speed control, and enclosures—not extreme buffers.

Odor / Emissions

Use	Typical Sources	Relative Level	Plain-English Notes
Paper Mill	Pulping/bleaching processes	High	Noticeable odors possible; controlled by process and scrubbers.
Chemicals / Petroleum	Volatile compounds, flares	High	Potential odors from handling and vents; tightly regulated.
Truck Freight Terminal	Diesel exhaust during peaks	Medium	Short-term diesel smell near loading areas and staging.
Quarry / Mining	Diesel equipment, blasting gases	Medium	Localized, episodic; depends on equipment and wind.
Data Center	Occasional generator testing	Low	Infrequent; scheduled tests, modern emissions controls.

Use operating schedules and emissions controls where applicable; data centers typically have minimal odor sources.

Traffic

Use	Trip Character	Relative Level	Plain-English Notes
Quarry / Mining	Heavy truck loads & hauling	High	Frequent truck traffic and dust on access roads.
Paper Mill	Shift traffic and freight trucks	Medium-High	Hundreds of employee trips daily plus shipping trucks.
Chemicals / Petroleum	Tanker and supply deliveries	Medium	Hazmat-regulated deliveries with designated routes.
Truck Freight Terminal	Constant tractor-trailer movement	High	Continuous semi traffic; staging yards run day and night.
Data Center	Staff cars & service visits	Low	Minimal daily trips; mostly technicians and security.

Traffic plans and routing solve impacts better than excessive setbacks.

Fire / Explosion Risk

Use	Typical Hazards	Relative Level	Plain-English Notes
Quarry / Mining	Explosives, blasting agents	High	Active use of explosives; requires state/federal oversight.
Paper Mill	Combustible dust, chemicals	Medium-High	Potential for process fires; heavy suppression systems.
Chemicals / Petroleum	Flammable liquids, gas handling	High	Highest hazard category; strict NFPA/EPA compliance.
Truck Freight Terminal	Fuel storage, maintenance	Medium	Diesel storage; welding/fire hazards in bays.
Data Center	Electrical gear, diesel backup	Low	Clean-agent fire systems; code-rated fuel tanks; no process chemicals.

Building and fire codes already control these risks without extra “special-use” mandates.

Summary

Across noise, dust, odor, traffic, and fire risk, data centers rank lowest among common I-3 uses. If I-3 standards are sufficient for heavy industry, they are more than adequate for data centers.

Data centers rank lowest in noise, particulate, odor, traffic, and fire risk among I-3 uses. All those land uses follow the same standards for noise, setbacks, height, and screening, and those rules work well.

If those rules are fair for heavier industries, why are data centers — which are quieter and cleaner — being singled out with several requirements that are even more stringent than those applied to other I-3 uses?

Every new rule that exceeds common sense — such as lower noise limits, increased setbacks, additional inspections, and extra bureaucratic hurdles — may seem harmless on paper. However, collectively, they make it more difficult and costly for Mason County landowners to develop their property productively.

That’s not protecting Mason County; it’s holding it back. Let’s be honest: the loudest voices calling for more restrictions are not those trying to earn a living from the land. Instead, they are individuals seeking to control their neighbors’ land to protect their own views.

Farm families and property owners who depend on their land for income deserve the freedom to adapt—whether that means leasing, selling, or responsibly developing new land uses, under fair and consistent regulations. Mason County’s progress has always come from welcoming new ideas that utilize local resources. If unnecessary regulations block new opportunities, we won’t protect our heritage; we will abandon it. Fair and balanced zoning doesn’t destroy our rural character. In fact, it helps keep Mason County lively and prosperous.

If we smother new opportunities under unnecessary regulations, we’re not preserving our heritage — we’re abandoning it.

Fair, balanced zoning doesn’t destroy our rural character.

It’s how we keep Mason County alive and working
