RE: PLAN REVIEW - Restaurant FACILITY NUMBER: 34007484
Malai Thai Restaurant
Dear Ms. Ruttanapaibooncharoen:
The Washington County Depaitment of Health and Human Services Environmental Health
Program has received plans for the proposed Malai Thai restaurant to be located at 14297 SW
Pacific Hwy in Tigard, Oregon.
The plans you submitted have been approved subject to the following conditions. If any future
changes are necessary during construction, the changes must be first approved by this office.
WATER AND WASTEWATER
It is our understanding that community water and community sewer are utilized at this facility.
A grease trap or interceptor is shown on your plans. A maintenance schedule must be developed
and followed to prevent grease from being disposed of in the sanitary sewer.
Your plans show a utility mopwashing sink or curbed floor receptacle. Facilities are required to
provide either a mopwashing sink or a curbed floor receptacle for the disposal of wastewater.
Piease submit a revised plan showing either a mopwashin sink or curbed floor receptacle. No
• other fixture may be used for disposal of mopwater. If you plan to install an automatic chemical
dispensing system at your mopwashing station, please contact the local Plumbing Authority for
information on the proper backflow device needed to protect your fresh water.
Please supply a mop - hanging device so mops and similar floor cleaning equipment can be cleaned
and hung between uses.
Be advised that your hot water heater must be of sufficient capacity to meet the peak hot water
demands of your facility. If hot water availability is found to be problematic, additional hot water
generating equipment will be required. Preliminary calculations show that your facility has a peak
demand of approximately 100 GPH. To meet this demand, the recommended minimum capacity of
the water heater would be either 55,000 BTU or 12 KW.

RESTROOMS
Your original plans show seating for 38 persons and your application shows that your plan was to
add seats. In order to add seats, you would be required to add a second restroom. Since you are not �II
willing to add an additional restroom, the maximum seats you can provide are fifteen.
One restroom is shown on the p lans. Please consult the local Building Department for information
on the ratio of toilets, urinals, and handwashing sinks required for your planned occupancy.
Restrooms must meet all the requirements as described in the Oregon Food Sanitation Rules for
design, construction, and operation. Restroom doors must self -close if they open onto a food or
dining area. There must be at least one covered waste receptacle in the women's restroom.
HANDWASHING
The plans you have submitted show one handwashing sink in the food service area. One
compartment of the three compartment sink will be required to be designated as a
handsink.
The number and placement of handwashing sinks must be adequate to serve all food service
activities including preparation, cooking, dishwashing, serving, bussing, bartending, and
restrooms. Use of handwashing sinks is restricted to handwashing only. Access to each sink
must be kept free for its intended use. Any adjacent work surfaces or clean utensils must be
protected through installation of a splash guard.
All handwashing sinks, including restroom handwashing sinks, must be equipped with dispensed
soap and towels. Common (cloth) towels cannot be used to dry hands. If disposable towels are
used, waste receptacles must be conveniently located near the handwashing facilities.
All handwashing sinks must be supplied with hot and cold water or tempered, water under

DISHWASHING AND SANITIZING
The plans show a dishwasher. The dishwasher is assumed to be a commercial model. Home style
dishwashers do not meet code requirements. Machine or water line mounted thermometers must be
provided to indicate water temperatures of the wash and rinse cycles. These thermometers must be
accurate to +2 °F or +1°C. The dishwasher must be capable of reaching proper wash and rinse
temperatures and must waste indirectly to a floor sink. If the dishwasher sanitizes with a boosted
high temperature rinse, the final rinse temperature must reach 160 °F or higher at the dish surface. If
a chemical sanitizer is used, it must meet the requirements of 21 CFR and be dispensed in proper
concentration. An accurate test kit is required to test the sanitizer concentration of the final rinse.
You must also have a method in place to clean and sanitize fixed food contact surfaces and
equipment. If wet wiping cloths are to be used, they must be kept in a clean rinse solution with an
approved sanitizer to prevent bacterial growth.

Plumbing Code, including the installation of backflow devices to protect the potable water supply.
The facility must also meet any additional requirements by the City of Tigard.

a floor sink or floor drain. This typically includes refrigerator condensation lines, ice machines, hot
water heaters, sinks used for food preparation, soda fountains, dishwashing machines, steam tables,
dipper wells, and espresso machines.
Where an air gap is required to prevent contamination from sewage backflow, the distance between
the bottom of the drain pipe and the rim of the floor sink or floor drain must be at least one inch or
two pipe diameters,. whichever is greater. Floor drains and floor sinks must remain accessible for
cleaning and maintenance.
Your plans indicate an indirect waste connection for the dishwasher, ice maker, soda fountain, and

may not be placed into any sink that does not waste indirectly with an approved air gap as described
above. The third compartment of a three- compartment sink may be utilized for food preparation
only if it wastes indirectly. Food may not be placed into sinks of incompatible use such as
handwashing sinks, mopwashing sinks, mop basins, or utility sinks.

bib to which hoses will be attached must be equipped with an approved backflow protection device.
