Proposal for Annual Emissions Sampling Page 1 of 3
Introduction
As requested by Mr. Rick Seanor of the City of Ukiah, this proposal describes the scope of work
and associated costs for conducting the annual emissions sampling of the perimeter gas -
extraction system at the City of Ukiah Landfill (Landfill).
In 1997, a perimeter gas -extraction system was installed at the Landfill to control the migration
of landfill gases away from the landfill. The system consists of vertical extraction wells
(between the landfill and the property line) connected to a header pipe. Landfill gas that has
migrated out of the landfill is collected by the wells, and then conveyed in the header to the
stack.
The collected gas is discharged without treatment, because a screening -level health -risk
assessment, conducted when the system was started, showed a less than 10 -in -one -million excess
cancer risk (the 10 -in -one -million limit was established by Mendocino County Air Quality
Management District [MCAQMD]).
The system is operating under a "Permit to Operate" issued by the MCAQMD. Condition
XIV.B.2. requires annual testing of stack gas for methane and the "specified air contaminants" of
the California Health and Safety Code, §41805.5, and reporting of the results to the MCAQMD
30 days before each permit renewal date (August 30 of each year). This condition requires
sampling and analysis by EPA TO -14 methodology. TO -14 analysis, however, is not appropriate
for methane and some of the specified air contaminants. The appropriate analytical methods are
described in the Scope of Work, below.
Special Condition XIV.B.3. states that if a health -risk assessment conducted by the MCAQMD
shows a greater than 10 -in -one -million excess cancer risk at the nearest receptor, the MCAQMD
may require treatment of the effluent. A health -risk assessment conducted now or in the future
would be based on the annual sampling conducted for Special Condition XIV.B.2.
Scope of Work
This scope of work addresses Special Condition XIV.B.2 (the annual emissions sampling) in the
Permit to Operate.
For all analyses, the system effluent will be sampled via a tee fitting attached to the sampling
port on the stack, inside the blower building. All samples will be collected in duplicate.
The formaldehyde samples will be collected using vacuum pumps constructed of stainless steel,
Teflon, Viton rubber, and Borosilicate glass, and designed for gas monitoring. Samples for
formaldehyde will be drawn through DNPH-coated silica -gel cartridges at about 1 liter/minute

for 6-8 hours. A field blank will be analyzed for formaldehyde. The field blank will consist of a
cartridge that remains in its culture tube next to the pumps during the duration of sampling.
Hydrogen sulfide will be collected in a tedlar bag, volatile organic compounds and fixed gases
will be collected in 6 -liter SUMMA canisters cleaned at the laboratory. Before sampling, the
canisters can hold a vacuum of up to -28 inches of mercury. The high vacuum allows sample to
be drawn into a canister, without the use of a pump, when the stainless-steel bellows valve on the
canister is opened.
All samples will be shipped overnight to Air Toxics, Ltd., Folsom, California. Air Toxics is a
California certified environmental laboratory.
Fixed (natural) gases and total nonmethane hydrocarbons (nonmethane organic compounds,
NMOC) will be analyzed by ASTM Method D-1945. The specified air contaminants of the
California Health and Safety Code, Part 4, Chapter 3, Article 2, Section 41805.5(i)(6) will be
analyzed by EPA Method TO -11 (for formaldehyde), EPA Method TO -14 (for halogenated
hydrocarbons), and ASTM D-5504 (for hydrogen sulfide).
Results will be presented in a written report containing field notes, laboratory sheets, tabulated
summaries of the data, and a discussion of results. The results also will be used to evaluate
compliance with Special Condition XIV.B.1, the emission limit for NMOC of 220 pounds/day.
The work does not include a health -risk assessment. If results from the proposed sampling are
similar to previous results (for which a health -risk assessment was conducted), presumably the
excess cancer risk of 10 -in -one million would not be exceeded. The City does not need to
conduct a health -risk assessment unless specifically requested to by the MCAQMD.
