Preliminary Observations from the HSI Study• Unused pharmaceutical management is a national interest of concern to state and

local pretreatment programs.• Management of the unused pharmaceuticals at hospitals and long term care facilities

is greatly influenced by Federal (CSA, RCRA, HIPPA) and state regulations (flush within 72 hours, stricter RCRA), ease of disposal method, and costs.

• Policies range from flushing leftover medicines to disposal to a reverse distributor for incineration.

Comments on Preliminary 2008 Plan • “Help is desperately needed for better disposal programs at hospice and home

healthcare.” (Nancy Busen, City of Bentonville, AR). • “No cost effective or efficient system exists for facilities to use to determine which

pharmaceuticals are classified as hazardous under RCRA, therefore facilities tend to flush pharm waste to the sewer system.” (Gus Changaris, EXP Pharmaceutical Services Corp)

Interim Report on Unused Pharmaceuticals in the Health Care Industry• On August 6th, EPA published an “Interim Report” that briefly summarizes

what EPA has learned to date from its study of unused pharmaceuticals from health care facilities: http://epa.gov/waterscience/ppcp/

Observations from the HSI Study:

• An ADA-funded study showed that approximately 50% of mercury entering POTWs is from dental offices (6.5 tons).

• Amalgam separators increase the amount of amalgam that is recycled (amalgam separators are at least 95% efficient).

• Use of amalgam separators generally results in reductions in POTW influent and biosolids mercury concentrations.

• Use of amalgam separators does not always result in reductions in POTW effluent since most amalgam particles are removed with biosolids (29-50% reduction in biosolids has been reported).

• Approximately 11 States and at least 20 local mandatory pretreatment programs require dental facilities to use amalgam separators.
