that ask you to describe certain aspects of your proposal. You do not need to repeat
those answers on this page. (Lead agencies may modify this form to include
additional specific information on project description.)
The Mason County Department of Community Development proposes to construct a
transfer station at the existing Mason County Landfill site o provide the necessary load out
facility for Mason County's Out waste transport a ntd disposal program (long-haul).
Waste handled at the proposed transfer station would he "acceptable waste," that is, only
residential and commercial solid waiste, construction and demolition debris, and wood waste
would he accepted. Ashestos and other ha7_ardt)Us wasteswould not be accepted. Facility
employees would he trained to identify and properly handle hazardous substances that may
illegally enter the facility. Any hazardous waste found wOuld he isolated and disposed of
properly.
Waste would he delivered in the following types of vehicles: commercial and municipal
compactor (packer) trucks, private (self-hauler) atutomoljiles, pickup trucks, trailers, and
commercial roll-off containers (drop boxes).
An average of 70 tons of waste per day would he consolidated at the transfer s ation and
loaded into long-haul trailers. Waste would he dumped from packer trucks and self-haul
vehicles onto a tipping floor, pushed across the floor with at wheeled battler, and gravity-
dropped through a dump chute into the top of the export trailers. A knucklehoom crane
would be used to redistribute and compact waste in the tra'ler to maximize its payload. The
Mason County Transfer Station
Environmental Checklist Pa,e 2 A9ay 1993
r
waste would be loaded into top loaded transport contain) rs, covered, and exported to a
regional landfill in eastern Washinoton or Oregon.
Waste collected at the existing remote transfer stations (13 Ifair, Hoodsport, Union) would
empty their dropoff containers at the proposed long-haul ransfer station on an as-needed
basis. Emergency storage capacity would he provided hv' spare trailers kept onsite at all
times. The transfer building itself would provide only wo eking storage for a sn►all portion
of the waste received daily.
12. Location of the proposal. Give sufficient information for a person to understand the
precise location of your proposed project, including a street addres
woulds, if`any, and
section, township, and range, if known. If a proposal would occur over range of
area, provide the range or boundaries of the site(s). Provide a legal description, site
plan, vicinity map, and topographic map, if reasonably available. While you should
submit any plans required by the agency, you are not required to duplicat maps or
detailed plans submitted with any permit applications related to this ch cklist.
This proposal is located at the Mason County Landfill site located about f ►ur miles
northwest of the City of Shelton. The existing landfill is located on a 77 acre . ite in the
southeast quarter of Section 4, Township 20 North, Ranee 4 West. Conceptual site designs
assume the transfer huilcling would he located in the former sludge pit are t to take
advantage of the grade differential required for trailer loa,,ling.

B. ENVIRONMENTAL ELEMENTS
1. Earth
a. General description of the site (circle one): Flat, rollin��, hilly, steep slopes,
mountainous, other
b. What is the steepest slope on the site (approximate p,, -cent slope)?
The steepest slope on the site is approximately 30 percen' and is located on thelsoutheast
corner of the landfill site.

muck)? If you know the classification of agricultural oils, specify them and note any
prime farmland.
The site is underlain by sandy gravels 70 to 90 feet deep. I These soils are not classified as
agricultural.

I
d. Are there surface indications or history of unstable so Is in the immediate vicinity'' If'
so, describe.
No. There are no surface indications or history of unst Lille soils in the immediate site
vicinity.
e. Describe the purpose, type, and approximate quan ities of any tilling or grading
proposed. Indicate source of fill.
Approximately 11,400 cubic yards (y') of excavation w )old he required for the truck
roadways and the transfer station building. Fill requir 'd for truck roadways would he
approximately 1,600 y;. Approximately 800 y` of strut Ural fill would he required for
construction of the transfer station huilding.
Fill would he generated on site from excavation activity. It the on-site material is found to
be unsuitable for structural fill, fill %could be imported from a local quarry.
f. Could erosion occur as a result of clearing, construction, or use'! It' so, generallN
describe.
Minor amounts of erosion could occur during clearing and construction due to wind and/or
rain. Use of the proposed transfer ,tatiun would not re. ult in further erosion. Finished
slopes would he hydroseeded and no steeper than 3 hori ontal: 1 vertical (3H: 1 V).
g. About what percent of the site Neill be covered with impervious surfaces after project
construction (for example, asphalt or buildings)?
The existing landfill and structures create approximately I ) acres of impervious s Lrfaces on
the 77 acre site (approximately !3 percent of the site). Less than an acre of iliperviOus
surfaces would be created under thi, proposal increasing impervious surfaces to less than
11 acres. After construction, imperious surfaces would increase to approximately 14
percent of the site.
h. Proposed measures to reduce or control erosion, or o her impacts to the eaOth if any:
Finished slopes would be no steeper th.Ln 31+ IV and hvdr')seeded for stahilizatio 1. Runoff
would be directed into a stormwater drain field designed t;o carry the maximum flow from
a 25-year storm event.

If any, generally describe and give approximate quantities if known.
Minor air emissions due to exhaust from construction eduipment Zuni partic1.11,1tes created
during construction activities would result from this grope sal.
During operation, the project would Uenerate approximately two additional round trip truck
trips per day. These additional truck trips would nunlmally- impact air duality. Eduipment
on site would be electrical and would produce no additional emissions. Miner diesel
emissions would he produced by wheeled loader on tippi Ig floor. Waste received at the
facility could generate odors if stored on site. These we old not he significant since the
waste would be exported daily.

generally describe.
No. There are no off-site sources of emissions or odor that may Affect this proposal.
c. Proposed measures to reduce or control emissions or other impacts to air, if' any:
The building would he naturally ventilated via the largo' proportion of open wall space
(chain link fencing and doorways). Dust along gravel roa Is would he controlled manually
by use of a fogging-type nozzle on a water hose.

approximately 2000 feet to the south. Due to the type of land uses and distance from
the site, these uses would not be impacted by construction or operation noise.
Off-site noise impacts should not be significant, and no mitigation measures are
proposed. Measures to control noise impacts to employees include:
Maintaining proper mufflers on vehicles and operating equipment.
Providing ear protection devices for operators.
