Section 2VAC5-690-210 - Design and capacity requirements for existing structures
Universal Citation: 2 VA Admin Code 5-690-210
Current through Register Vol. 41, No. 3, September 23, 2024
A. An existing containment structure must comply with the following material specifications:
1. The containment structure must be
constructed of steel, reinforced concrete, or other rigid material capable of
withstanding the full hydrostatic head, load, and impact of any pesticides,
precipitation, other substances, equipment, and appurtenances placed within the
structure. The structure must be liquid-tight with cracks, seams, and joints
appropriately sealed.
2. The
structure must not be constructed of natural earthen material, unfired clay, or
asphalt.
3. The containment
structure must be made of materials compatible with the pesticides stored. In
this case, compatible means able to withstand anticipated exposure to stored or
transferred substances and still provide containment of those same or other
substances within the containment area.
B. An existing containment structure must comply with the following general design requirements:
1. The owner or operator must ensure that
appurtenances and pesticide containers are protected against damage from
operating personnel and moving equipment. Means of protection include, but are
not limited to, supports to prevent sagging, flexible connections, the use of
guard rails, barriers, and protective cages.
2. All appurtenances, discharge outlets, and
gravity drains through the base or wall of the containment structure must be
sealed, except for direct interconnections between adjacent containment
structures that meet the requirements of Part V (2VAC5-690-160 et seq.) of this
chapter.
3. The containment
structure must be constructed with sufficient freeboard to contain
precipitation and prevent water and other liquids from seeping into or flowing
onto it from adjacent land or structures.
4. Multiple stationary pesticide containers
may be protected within a single secondary containment unit.
C. An existing secondary containment unit for a stationary container of liquid pesticides and an existing containment pad in a pesticide dispensing area must comply with the following capacity requirements:
1. Existing
secondary containment units for stationary containers of liquid pesticides must
have a capacity of at least 100% of the volume of the largest stationary
pesticide container plus the volume displaced by other containers and
appurtenances within the unit.
2.
Existing containment pads in pesticide dispensing areas that have a pesticide
container or pesticide-holding equipment with a volume of 750 gallons or
greater must have a holding capacity of at least 750 gallons.
3. Existing containment pads in pesticide
dispensing areas that do not have a pesticide container or pesticide-holding
equipment with a volume of at least 750 gallons must have a holding capacity of
at least 100% of the volume of the largest pesticide container or
pesticide-holding equipment used on the pad.
D. Each stationary container of liquid pesticides protected by an existing secondary containment unit must be anchored or elevated to prevent flotation in the event that the secondary containment unit fills with liquid.
E. Each existing containment pad in a pesticide dispensing area must:
1. Be designed and constructed to intercept
leaks and spills of pesticides that may occur in the pesticide dispensing
area.
2. Have enough surface area
to extend completely beneath any container on it, with the exception of
transport vehicles dispensing pesticide for sale or distribution to a
stationary pesticide container. For such vehicles, the surface area of the
containment pad must accommodate at least the portion of the vehicle where the
delivery hose or device couples to the vehicle. This exception does not apply
to transport vehicles that are used for prolonged storage or repeated onsite
dispensing of pesticides.
3. Allow,
in conjunction with its sump, for removal and recovery of spilled, leaked, or
discharged material and rainfall, such as by a manually activated pump.
Automatically activated pumps that lack automatic overflow cutoff switches for
the receiving container are prohibited.
F. An existing secondary containment unit for a stationary container of a dry pesticide must comply with the following specific design requirements:
1. The
stationary containers of dry pesticides within the containment unit must be
protected from wind and precipitation.
2. Stationary containers of dry pesticides
must be placed on pallets or a raised concrete platform to prevent the
accumulation of water in or under the pesticide.
3. The storage area for stationary containers
of dry pesticides must include a floor that extends completely beneath the
pallets or raised concrete platforms on which the stationary containers of dry
pesticides must be stored.
4. The
storage area for stationary containers of dry pesticides must be enclosed by a
curb a minimum of six inches high that extends at least two feet beyond the
perimeter of the container.
