2005 CERCLA Priority List of Hazardous Substances
Comprehensive Environmental Response and Liability Act exempts commercial fertilizer.

Therefore, it is EPA's opinion that, "If the placement of sludge on land were considered to be "the normal
application of fertilizer," that placement could not give rise to liability under CERCLA."  --- "Under CERCLA, protection
from liability is also provided when there is a release of a CERCLA hazardous substance and the release occurs
pursuant to Federal authorization. (FR. 58, p. 9262 - 40 CFR 257/503)

"The Agency recognizes that today's rule [part 503] may not regulate all pollutants in sewage sludge that
may adversely effect public health and the environment." (1993-FR. 58, 9253)

"EPA concluded that adequate protection of public health and the environment did not require the adoption
of standards designed to protect human health or the environment under exposure conditions that are
unlikely and where effects were not significant or widespread." (FR. 58, p. 9252) (Farm, home, garden)

What is the CERCLA List?

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) section 104 (i), as amended
by the Superfund Amendments and Reauthorization Act (SARA), requires ATSDR and the EPA to prepare a list, in order
of priority, of substances that are most commonly found at facilities on the National Priorities List (NPL) and which are
determined to pose the most significant potential threat to human health due to their known or suspected toxicity and
potential for human exposure at these NPL sites. CERCLA also requires this list to be revised periodically to reflect
additional information on hazardous substances
