2 FACILITY DESCRIPTION

Hill AFB Main Base is located in Davis and Weber Counties approximately 30 miles north of Salt Lake City and comprises approximately 6,600 acres including the Little Mountain Facility, a remote test facility located approximately 18 miles northwest of the Main Base. The Main Base provides worldwide logistics support for some of the Air Force and Defense Department's most sophisticated weapon systems. Support operations include systems management, spare parts, and major maintenance and modification services. Hill AFB has extensive industrial facilities for painting, paint stripping, plating, parts warehousing/distribution, and wastewater treatment. In addition, Hill AFB manages and maintains other systems such as conventional air munitions, solid propellants, landing gear, and training devices.

Operations at the Main Base (excluding the Little Mountain Facility) that have the potential to generate fugitive dust consist of temporary construction and demolition activities, operation of a 25‐acre landfill, cleared open areas, paved and unpaved roads, and operation of a sand and rock product storage area.

Operations, at the Little Mountain Facility with the potential to generate fugitive dust, consists of temporary construction and demolition activities, cleared open areas, as well as paved and unpaved roads. Details of fugitive dust activities are provided in Section 3, the duration of these activities is provided in Section 4, the controls used for these activities are provided in Section 5.

3 FUGITIVE DUST ACTIVITIES

This section describes the activities and operation of sources at Hill AFB Main Base (including the Little Mountain Facility) that could potentially result in the generation of fugitive dust. Figures 1 and 2, located at the end of this plan, provide maps of the Main Base and the Little Mountain Facility, respectively, for stationary sources of interest.

3.1 CONSTRUCTION AND DEMOLITION ACTIVITIES

Construction and demolition activities occur periodically throughout the Main Base. Fugitive dust associated with these activities includes: the handling and transfer of material, loading, hauling, and dumping of material, clearing and leveling of land, minor drilling and pushing operations, earth moving and excavation of land, development construction, road construction, and potential crushing of construction or demolition debris. Construction activities associated with fugitive dust also include the use of equipment such as bulldozers, cranes, loaders, dump trucks, compactors, compressors, excavators, and graders.

3.2 LANDFILL

Hill AFB operates and maintains a 25‐acre Class IVb Landfill located at the northern end of the Main Base. Fugitive dust associated with normal operation of the landfill includes storage, handling, and transfer of material, dumping of material, and application of soil caps. Operation of the landfill is limited to receipt of construction and demolition debris from operations conducted throughout the Main Base.

The landfill consists of three cells: (1) a 15‐acre concrete cell for disposal of concrete debris and excavated soils generated at Hill AFB, (2) a 7.5‐acre asphalt cell containing asphalt and excavated soils generated at Hill AFB that are stored for recycling (recycled asphalt is used as fill in construction projects and as aggregate on unpaved roads at Hill AFB), and (3) a 2.5‐acre wood cell that consists of operation of a wood grinding machine to chip used wood such as pallets, crates, and dead trees (chips are used as mulch in landscaping projects, as cover for side slopes in the concrete cell, and as cover in restoration projects around the base). The wood chipper operates an average of one day per month (Hill AFB, 1999).

3.3 OPEN AREAS

There are very few open areas at the Main Base greater than one‐quarter acre that are not already vegetated. The majority of these areas do not generate fugitive dust.

3.4 PAVED ROADS

Approximately 96% of the roads at the Main Base (including the Little Mountain Facility) have been paved to support operations and minimize generation of fugitive dust. Construction activities that occur periodically throughout each of these areas have the potential to deposit materials and generate minor amounts of fugitive dust.

3.5 UNPAVED ROADS

A small number of unpaved roads exist at the Main Base (including the Little Mountain Facility). Fugitive dust associated with vehicular traffic on unpaved roads is minor and includes blowing dust.

3.6 SAND AND ROCK PRODUCT STORAGE AREA

Hill AFB Main Base operates and maintains a small material storage area used to store miscellaneous piles of sand and rock products used for construction projects throughout the base. Fugitive dust associated with the sand and rock product piles includes blowing dust, handling and transfer of material, and the loading and dumping of material.

4 ACTIVITY DURATION

The length of Hill AFB fugitive dust activities is indefinite. The duration of construction and demolition projects will vary depending upon the nature and level of activity; however, most construction and demolition activities are limited to a six‐month period. Operation of the wood and asphalt cells of the landfill is also indefinite, as material is continually recycled. Operation and design of the concrete landfill limits disposal of material to 1 million cubic yards or 2 million tons of construction debris, however use of the concrete landfill is indefinite in duration. The use and maintenance of paved and unpaved roads, the use of cleared open areas (such as perimeter firebreaks), and the operation of the sand and rock product storage area are indefinite in duration. This plan has been designed to control fugitive dust at Hill AFB regardless of the activity duration.

5 FUGITIVE DUST CONTROLS ON SITE

This section describes the control strategies used at Hill AFB to control fugitive dust from sources identified in Section 4 of this document. The strategies employed at Hill AFB are designed to meet the on‐site 20% fugitive dust opacity limit and the 10% property boundary fugitive dust opacity limit of UAC R307‐309‐5. Per UAC R307‐309‐12, records demonstrating compliance with R307‐309 will be maintained for all dust‐generating sources subject to R307‐309‐5(2) and (3), and those records will be maintained on file for a period of 5 years.

CONTINGENCY DUST CONTROLS IF WIND > 25 MPH

The opacity requirement of UAC R307‐309‐5 will not be applicable during high wind events if Hill AFB complies with this fugitive dust control plan and administers at least one of the following dust control contingencies listed below when the wind speed exceeds 25 mph:

Pre‐event watering, or

Hourly watering, or

Cease or reduce fugitive dust producing operations.

5.1 CONSTRUCTION AND DEMOLITION ACTIVITIES
