(i) 
Waste Disposal 
 
Best management practices shall be implemented to minimize the discharge of litter, 
debris, building materials, hardened concrete waste, or similar materials to waters of 
the State.  A narrative of these practices shall be provided in the Plan. In addition, the 
dumping of liquid wastes in storm sewers is prohibited. 
 
(ii) Washout Areas 
 
Washout of applicators, containers, vehicles and equipment for concrete, paint and 
other materials shall be conducted in a designated washout area.  There shall be no 
surface discharge of washout wastewaters from this area.  Such washout shall be 
conducted: (1) outside of any buffers and at least 50 feet from any stream, wetland or 
other sensitive resource; or (2) in an entirely self-contained washout system.  The 
permittee shall clearly flag off and designate areas to be used for washing and conduct 
such activities only in these areas.  The permittee shall direct all washwater into a 
container or pit designed such that no overflows can occur during rainfall or after 
snowmelt.  At least once per week, the permittee shall inspect all of the containers or 
pits used for washout to ensure structural integrity, adequate holding capacity, and to 
check for leaks or overflows. If there are signs of leaks, holes or overflows in the 
containers or pits that could lead to a discharge, the permittee shall repair them prior to 
further use. 
 
For concrete washout areas, the permittee shall remove hardened concrete waste 
whenever the hardened concrete has accumulated to a height of ½ of the container or 
pit or as necessary to avoid overflows.  The permittee shall remove and dispose of such 
hardened concrete waste in accordance with the practices developed for “Waste 
Disposal” (see Section 5(b)(2)(D)(i) of this general permit).   
 
A narrative of maintenance procedures and a record of maintenance and inspections 
shall be included in the Plan. 
 
(iii) Off-site Vehicle Tracking/Dust Suppression 
 
Off-site vehicle tracking of sediments and the generation of dust shall be minimized. 
Wet dust suppression shall be used, in accordance with section 22a-174-18(c) of the 
Regulations of Connecticut State Agencies, for any construction activity that causes 
airborne particulates. The volume of water sprayed for controlling dust shall be 
minimized so as to prevent the runoff of water. No discharge of dust control water shall 
contain a visible oil sheen, floating solids, visible discoloration, or foaming agents or 
cause a visible sheen, floating solids, visible discoloration, or foaming in any receiving 
waters. 
 
(iv) Cleaning 
 
All post-construction stormwater structures shall be cleaned of construction sediment 
and any remaining silt fence shall be removed upon stabilization of the site. 
 
(v) Storage of Chemical and Petroleum Products 
 
All chemical and petroleum product containers stored on the site (excluding those 
contained within vehicles and equipment) shall be stored within an impermeable 
containment system that is free of gaps and cracks, can contain any leaks or spills and 
accumulated precipitation until the collected materials are detected and removed, and

(vii) 
When a mobile source is in queue to be inspected by U.S. military 
personnel prior to gaining access to a U.S. military installation.   
 
(c)  
Control of airborne particulate matter and fugitive particulate matter. 
 
(1)  
No person shall cause or allow any materials to be handled, transported, or stored; or a 
building, its appurtenances, or a road to be used, constructed, altered, repaired or demolished 
without taking reasonable precautions to prevent particulate matter from becoming airborne.  
Such reasonable precautions shall be in accordance with good industrial practice as determined 
by the commissioner and shall include, but not be limited to: 
 
(A) 
The use of water or other appropriate material to prevent airborne particulate 
matter generated by the demolition of buildings or other structures; construction 
operations; the clearing or grading of land; or the grading, construction or 
improvement of roads; 
 
(B) 
The application of asphalt, water, suitable materials or covers to material 
stockpiles and other surfaces that can give rise to airborne particulate matter; 
 
(C) 
The use of hoods, fans, fabric filters or other devices to enclose and vent the 
handling of materials that can give rise to airborne particulate matter; 
 
(D) 
The covering, while in motion, of open-bodied trucks, open-bodied trailers and 
railroad cars transporting materials capable of giving rise to airborne particulate 
matter; 
 
(E) 
The prompt removal of earth or other material deposited onto paved streets by 
trucking, earth moving equipment, erosion or other means; and 
 
(F) 
The use of containment methods for sandblasting or similar operations. 
 
(2) 
No person shall cause or allow the emission of visible particulate matter beyond 
the legal boundary of the property on which such emission occurs that either: 
 
(A) 
Remains near ground level beyond such property boundary; or 
 
(B) 
Diminishes the health, safety or enjoyment of people using a building or structure 
located beyond the property boundary.   
 
(3)  
No person shall emit particulate matter into the ambient air in such a manner as to cause a 
nuisance.
