,all CITY OF FORT WORTH FACILITIES
Effective December 22, 1988, the U.S. Environmental Protection Agency (EPA)
finalized new regulations for underground storage tanks (UST) which contain
either petroleum or certain hazardous substances. The regulations were
developed because it was found that a significant percentage of tanks leak
and threaten to contaminate groundwater. The new regulations require
affirmative steps for modernizing tank systems, monitoring and responding
to releases, and notifying EPA in the event of a confirmed or suspected leak.
They also require tank owners and operators to properly design and construct
systems, protect them from corrosion, provide for spill and overflow
protection, and to operate a leak detection system.
The following indicates minimimum requirements and specific deadlines provided
for in the UST regulations:
Leak Detection

Every 5 Years (You can only use this choice for
10 years after installation)

The City of Fort Worth has one hundred eleven underground storage tanks that
range in capacity from 275 to 25,000 gallons. These tanks are located at
fifty-four different sites and were installed between 1950 and 1987.
Thirty-three storage tanks are located at Equipment Services Division service
centers, fifty-three storage tanks are located at fire stations, and the
remaining tanks are located at Aviation, Park and Recreation, and Electronics
Division facilities.
Depending on the age of the tank, the underground storage tank regulations
require that retrofitting, replacement, and/or other action be initiated
by December 1989 and be continued through December 1998 until all existing
tanks are provided with leak detection, corrosion protection

CITY OF FORT WORTH FACILITIES
Because of the extent and complexity of the problem, it is believed that
the City should contract with an outside engineering and consulting firm
with extensive knowledge and experience in this field to (1) inventory the
City's underground storage tanks, (2) develop a program and schedule that
will enable the City to comply with the underground storage tank regulations,
and (3) develop specifications and contract documents to obtain the services
necessary to do the required work on the tanks. Actual retrofitting and/or
replacement of tanks along with any needed testing and cleanup activities
will be handled through separate contracts and submitted to the City Council
for approval. As we go through this process we will be looking at ways to
reduce the number of underground tanks that we have and other measures to
reduce the City's liability in this area.
"The T" has eight underground storage tanks which must be brought into
compliance with the new EPA regulations. The general manager for "The T"
has requested that these tanks be included in the scope of work that the
City is proposing and has indicated that "The T" will pay its share of the
costs.
If the City Council concurs, staff will proceed to develop a request for
proposal to obtain these services. Funding and other more specific information
concerning this project will be provided after proposals are received and
reviewed.
