Generic Environmental Classification Document (ECD)
For State Agencies*

Prepared Pursuant to Section 22a-1a-4
of the Regulations of Connecticut State Agencies (RCSA)

I. Typical Actions For Which Environmental Impact Evaluations Shall Always Be Prepared.  Such actions may include, but are not limited to, instances where the State is obligating the following types of development through State funding or agreements:

a. Construction of new sewage treatment plants;

b. Construction of hazardous waste disposal facilities;

c. Construction of low-level radioactive waste disposal facilities; and

d. Construction of coal-fired heating plants.

II. Typical Actions Whose Degree of Impact Is Indeterminate, But Could Have Significant Environmental Impacts.  When any of the following actions are proposed, including, but not limited to, instances where the State is obligating the following types of development through State funding or agreements, the sponsoring agency shall conduct an early public scoping process in accordance with Section 22a-1b(b) of the Connecticut General Statutes (CGS).  The sponsoring agency shall take into consideration comments received and shall prepare a written memorandum that documents its findings and subsequent determination of the proposed actionís environmental significance using the criteria set forth in Section 22a-1a-3 of the Regulations of Connecticut State Agencies.  Said memorandum shall be posted in the Environmental Monitor, unless the sponsoring agency determines that an environmental impact evaluation shall be prepared pursuant to CGS Section 22a-1b(c).

a. Construction of, addition to, or major alteration involving a change in use of a State leased, licensed, or owned facility involving 100,000 sq. ft. or greater of floor space if the facility is located in a Regional Center or Neighborhood Conservation Area, or 25,000 sq. ft. or greater of floor space if the facility is located outside of such areas as defined by the locational guide map of the Conservation and Development Policies Plan for Connecticut.  A facility is defined as one or more concurrently planned or envisioned structures on a site, the sum total of which would equal or exceed the applicable figure for the project location;

b. Construction of new paved roads or lane additions to existing roads where the Stateís cost of such which would equal or exceed one million dollars ($1,000,000) using current industry cost estimates;

c. Construction of new parking lots, garages, or additions thereto, that provide for an increase in capacity of 200 vehicles or more;

d. Construction of new, or changes to, dams on watercourses resulting in a permanent change in water level of more than four (4) inches;

e. Capacity expansion of sewage treatment plants, hazardous waste or low level radioactive disposal facilities and coal fired heating plants;

f. Demolition or major alteration of any facility (i.e., building or structure) or site listed or eligible to be listed on the National or State Registers of Historic Places as determined by the State Historic Preservation Office; and

g. Any other action that may significantly affect the environment in an adverse manner.  The significance of a likely consequence of an action should be assessed by the sponsoring agency and/or the participating agency, as the case may be, in connection with its setting, its probability of occurring, its duration, its irreversibility, its controllability, its geographic scope, its magnitude, and regulatory requirements.

III. Any and all joint federal/state actions for which environmental assessments or environmental impact statements are prepared pursuant to the National Environmental Policy Act (NEPA), as amended, shall be recognized as meeting the Connecticut Environmental Policy Act (CEPA) requirements provided that such NEPA documents meet, and are circulated in accordance with, the CEPA document-equivalent requirements.

IV. Actions which do not warrant a review pursuant to CEPA.  Notwithstanding the provisions of II.f. above, the following actions have been shown by past agency experience to have impacts which are determinate, sufficiently limited in scope or covered under specific state or federal requirements other than CEPA or NEPA, and include a determination by the State Historic Preservation Office, whenever appropriate, that there is either No Effect or No Adverse Effect to historic, architectural or archaeological resources.


a. Maintenance, repairs, or renovations of facilities;


b. Demolition of facilities;


c. Environmental remediation at facilities or property;


d. Energy conservation measures; and


e. Licenses for non facility-related purposes.



* Each agency that currently has its own ECD (i.e., DECD, DOT, DEP & DPH) shall either revise its ECD in accordance with RCSA Sec. 22a-1a-6 by April 1, 2011 or operate under the provisions of this Generic ECD after such date.
