EFFECTIVE DATE: November 1, 2005
POLICY DESCRIPTION: Environmental –
Wastewater Discharge
REPLACES POLICY DATED: 1/12/1999
POLICY NUMBER: DC.013
SCOPE: All Company-affiliated facilities including hospitals, ambulatory surgery centers,
outpatient imaging centers, medical office buildings, home health agencies, physician practices, and
all Corporate Departments, Groups and Divisions and on-site subcontractors.
PURPOSE: To require that each facility properly manages wastewater discharge in accordance with
applicable U.S. Environmental Protection Agency (EPA) regulations.
POLICY:
1. Facilities must properly manage wastewater discharge in accordance with applicable EPA
regulations, as well as state laws and regulations that may impose additional compliance
requirements. Each facility should consult with HCA Facility Management and Engineering
Services and the facility’s Operations Counsel to identify additional requirements.
2. Municipal wastewater treatment plants control discharge into city/county sewers. Discharge of
priority pollutants and certain chemicals are normally prohibited by the municipality. A facility
must review in detail the prohibited discharges contained in the local sewer use ordinance. The
facility’s hazardous waste management plan must list those materials that cannot be flushed down to
the sewer.
3. If a facility treats and discharges wastewater directly to lake, river, ocean, or cistern, the facility must
hold a Nation Pollutant Discharge Elimination System (NPDES) permit. The facility must comply
with all permit conditions listed in the NPDES permit.
4. If a facility is classified as a significant industrial user, and the municipal wastewater system requires
a pretreatment permit, facility personnel must implement a monitoring program as required in the
pretreatment permit.
5. Facilities must skim grease or floatable substances from wastewater discharged to public sewers.
6. If a fuel spill occurs that reaches the sanitary sewer or a storm sewer, facility personnel must
activate the environmental emergency response plan, and the city/county wastewater treatment
plant must be notified immediately.

REPLACES POLICY DATED: 1/12/1999
POLICY NUMBER: DC.013
PROCEDURE:
1. Each facility must have a pretreatment permit from the city/county, an NPDES permit from the state
water control agency, or verification that a pretreatment permit from the municipality is not required.
2. If a facility is subject to a pretreatment permit or NPDES permit, monitoring and effluent testing
must be performed by a certified laboratory in accordance with the permit conditions.
3. Facilities must separate waste materials containing metals (such as silver, lead, barium, and mercury)
and organic solvents (such as xylene, formalin) from the wastewater and dispose of them separately
as hazardous waste.
4. Facilities must not discharge petroleum products, such as gasoline, diesel, kerosene, and used motor
oil to the wastewater.
5. Facilities must properly and safely dilute acid discharges to the sanitary sewer with copious amounts
of water.
6. Facilities must never connect roof drains, sump discharge, parking lot drains, or storm water
catchments to the sanitary sewer.
7. Facilities that discharge wastewater containing grease or floatable substances must install grease
traps to skim off the grease before wastewater can be discharged to the public sewer. Facility
personnel must carry out proper maintenance of the grease trap and proper disposal of waste grease.
8. Facilities must implement silver recovery in the Radiology Department where film processing
units are in operation.
9. If a facility plans to start a construction project that will disturb more than 5 acres of land, the
construction manager responsible for the project must obtain, or have the general contractor
obtain, an NPDES storm water discharge permit from EPA and/or the state, at least 90 days
before the site work starts. Permit conditions must be met during the construction. After
construction is complete, a certificate of completion must be filed with EPA and/or the state by
the construction manager, general contractor, or architect. A copy of this NPDES permit and the
certificate of completion must be provided to HCA Facility Management and Engineering
Services.
RECORDKEEPING:
A compliance file must include at least:
