464 Waste Management Practices: Municipal, Hazardous, and Industrial
● An artificial or natural barrier (e.g., fence or berms), which completely surrounds the
active portion of the facility
● A means to control entry, at all times, through the gates or other entrances (e.g., an atten-
dant, television monitors, locked entrance, or controlled roadway access)

Signs with the warning ‘‘Danger — Unauthorized Personnel Keep Out” must be posted at each
entrance (Figure 14.1). The warning must be written in English and in any other language predom-
inant in the area surrounding the facility. Therefore, in northern Maine it may be suitable to post
signs in French and in Texas to post signs in Spanish.

14.3.4 INSPECTIONS
The facility operator is required to inspect the facility for malfunctions, deterioration, and oper-
ator errors that may lead to a release of hazardous wastes or pose a threat to public health. These
inspections must be scheduled often to identify and correct problems on time. The schedule
must identify potential problems to be checked, the date and time of each inspection, the name
of the inspector, a list of observations, and the date and types of any repairs or other actions. A
written schedule for inspecting monitoring equipment, safety and emergency equipment, secu-
rity devices, and operating and structural equipment must be kept on file at the facility. The
inspections must be recorded in an inspection log and these records must be maintained for at
least 3 years.
Inspection frequency may vary for items on the schedule; however, the frequency must be based
on the rate of possible deterioration of the equipment and the probability of an environmental or
public health incident if the deterioration or malfunction goes undetected between inspections.
Inspection frequencies for certain equipment as specified in the regulations are listed in Table 14.2.
Because of its uniqueness, each facility should develop its own inspection logs that identify the spe-
cific items to be inspected and their frequency of inspection.

14.3.5 REACTIVE AND IGNITABLE WASTES
A TSDF is required to take precautions to prevent accidental ignition or reaction of ignitable or
reactive waste. This waste must be separated and protected from sources of ignition. A facility that
