To Whom It May Concern:

California has published a list of over 900 chemicals, including naturally occurring substances used in

manufacturing and processing of products that are known to the State to cause cancer or birth defects or other

reproductive harm.

It is the responsibility of the manufacture to review this list and to advise its customers of the potential that

their products might contain trace amounts of one or more of these chemicals. Spruce Environmental

Technologies, Inc. takes this responsibility seriously and strives to produce products that meet or exceed

governmental standards. We continually review our materials of construction and manufacturing processes to

ensure compliance with such standards.

As such, Spruce Environmental Technologies, Inc. is providing this letter as acknowledgment that the following

chemicals are known to exist in some of the components that are used in the construction of our inline radon

And according to California Safe Drinking Water and Toxic Enforcement Act of 1986, warning labels are

required either on the end product or in place of use and are to be supplied by the companies producing

products constructed with chemicals from the list. However, this is only necessary when exposure to a

chemical is a given and that exposure is above set limits. If daily exposure to a chemical at a level which does

not exceed the set limit of micrograms/day, such chemical shall be deemed to pose no significant risk per the

language of the Act.
