STATE OF CONNECTICUT

DEPARTMENT OF ENVIRONMENTAL PROTECTION

In the matter of

The State of Connecticut and

The Connecticut Light

and Power Company

Trading Agreement

and Order No. 8162

Whereas, the Commissioner of Environmental Protection

("Commissioner") and The Connecticut Light and Power Company

("CL&P") agree that it is in the public interest that they work

cooperatively to improve the air quality within the State of

Connecticut and that the use of emission reduction trading will

achieve this result in a timely and cost-effective manner:

A. At the request and with the agreement of CL&P, the

Commissioner finds the following:

1. CL&P is an electric utility with headquarters in

Berlin, Connecticut, which owns and operates four

fossil fuel-fired electric generating stations within

the state.

2. One of the four fossil fuel-fired electric generating

stations within the state that CL&P owns and operates

is Middletown Station at 1866 River Road in Middletown,

Connecticut {"facility"}. At the facility, CL&P

operates Middletown Station Unit 3, a 245 megawatt

cyclone boiler on No. 6 fuel oil and/or natural gas,

Connecticut Registration Number 104-0100, ("boiler").

A continuous emissions monitor ("CEM"), certified to 40

Code of Federal Regulations Part 75, measures nitrogen

oxide ("NOx")emissions from the boiler.

3. During the year 1981, prior to modifications of the

boiler's burner, combustion controls and operating

conditions, and prior to the installation of natural

gas operating capabilities, and based on Department of

Environmental Protection approved stack test data, the

average annual NOx emission rate for Middletown Station

Unit 3 was 0.876 pounds per million British thermal

units ("lbs/MMBtu") of heat input when operating on No.

6 fuel oil. On and after May 31, 1995, the Regulations

of Connecticut State Agencies ("Regulations") require

that the boiler emit NOx at a rate no greater than 0.43

lbs/MMBtu of heat input when operating on No. 6 fuel

oil and 0.43 lbs/MMBtu of heat input when operating on

natural gas.

4. In January 1994, CL&P completed modifications of the

boiler's burner and combustion controls, and began to

test and adjust operating conditions, thereby reducing

the boiler's NOx emission rates below its permitted,

allowed and actual baseline emission rates. Natural

gas operating capabilities were installed at the

facility by July, 1997 to provide further reductions of

NOx emissions. Such modifications and installation

capabilities enabled CL&P's boiler to frequently meet

and operate below the emission limitation specified in

Section 22a-174-22(e)of the Regulations.

5. After November 1, 1996, CL&P may obtain approval of

actual reductions in NOx emissions, generated by

operating the boiler at a rate which is below 0.43

1bs/MMBtu of heat input when operating on No. 6 fuel

oil and 0.43 lbs/MMBtu of heat input when operating on

natural gas for use as emission reduction credits

("ERes") .

6. Pursuant to Section 22a-174-22(j) of the Regulations,

CL&P intends to acquire and generate approved ERCs

until May 1, 2003 at the facility. Approved ERCs are

defined for purposes of this Trading Agreement and

Order as those for which the Commissioner has provided

written authorization for use in compliance with

Section 22a-174-22 of the Regulations. CL&P will

acquire approved ERCs monthly on an as-needed basis, as

determined by actual NOx emissions in the event that

the 24-hour average exceeds the NOx emission

limitations of Section 22a-174-22{e) of the

Regulations.

and as computed in accordance with the terms of this

Trading Agreement and Order, will conform to the

requirements of Section 22a-174-22 (j) (3) of the

Regulations. Specifically, the reductions will be:

because they result in a reduction of actual

emissions released into the air, net of any

consequential increase in actual emissions resulting

from shifting demand. The emission reductions are

properly measured, recorded and reported.

Ouantifiable because they are based on continuous

emission monitoring data as applied in an appropriate

reliable and replicable protocol, providing the rate

and total mass amount of reduction.

Surplus because they are not required by any

Connecticut statute or regulation mandated by a current

State Implementation Plan ("SIP"), and are not

currently relied upon in any applicable attainment

plan, any reasonable further progress plan or milestone

demonstration.

Permanent because the advanced control system and

installation capabilities are in place and operating,

and an appropriate tracking system is in place to

monitor all data required to verify and quantify the

creation of ERCs.

Enforceable because the ERCs are approved by the

Commissioner retrospectively after the submission by

CL&P of the quarterly or semi-annual report that will

document their creation.

8. As documented in Attachment 1, attached to and

incorporated by reference into this Trading Agreement

and Order, 288 ERCs were created by the boiler between

November I, 1996 and September 30, 1997 (54 during the

ozone season and 234 during the non-ozone season).

This number of ERCs takes into consideration the ten

Trading Agreement and Order, pursuant to Section 22a-174-

22(d) (4) of the Regulations, will allow CL&P and approved

sources within Connecticut to use 288 tons of NOx ERCs

referenced in paragraph A.8. of this Trading Agreement and

Order (54 during the ozone season and 234 during the nonozone season) for purposes of compliance under Section 22al74-22(j) and/or Section 22a-174-3(1) (5) of the Regulations

to achieve a portion of the nitrogen oxide emission

reductions required or as emission offsets for new sources.

Upon sufficient documentation as prescribed below, the

Commissioner may provide written approval of additional ERCs

by CL&P retrospectively. Approved ERCs created by CL&P may

be held by CL&P or transferred to other persons. Such ERCs

shall remain valid until they are used or until May 1, 2003,

whichever occurs first.

C. With the agreement of CL&P, the Commissioner, acting under

Sections 22a-6, 22a-171, 22a-174, 22a-l76, and 22a-177 of

the Connecticut General Statutes, orders CL&P as follows:

1. ERe generatioo. For purposes of generating ERCs from

the boiler at the facility, CL&P shall use 0.43

lbs/MMBtu of heat input when operating on No. 6 fuel

oil and 0.43 lbs/MMBtu of heat input when operating on

natural gas as the baseline emission rate for the

boiler. When calculating ERCs, CL&P shall use the

lower of CEM-recorded NOx emission rate* or actual fuel

usage data for the boiler in MMBtu/day, when

determining heat input. Ten (10) percent of all ERCs

(tons) created by the boiler shall be retired by the

facility and permanently removed from all calculations

on a daily basis to assure a benefit to the

environment.

*This rate shall be calculated pursuant to the methodology

described in 40 Code of Federal Regulations Part 75.

4 Date:

2. ERe Use. Approved ERCs shall be acquired for the period

beginning June 1, 1995 and continuing until CL&P

achieves permanent compliance for the boiler with the

emission standards in Section 22a-174-22(e) of the

Regulations or until May 1, 2003, whichever occurs

first. CL&P shall acquire approved ERCs, and document

and record the amounts of NOx emissions and ERCs used

by the boiler each month, and shall maintain and

provide such records in accordance with the following

and Section 22a-174-4 of the Regulations, until May 1,

2003:

a. Before the first day of each month, calculate

projected worst case ERCs required for the same

calendar month as follows:

ERCs (tons) = {[estimated worst case NOx emission

rate in Ibs/MMBtu - ((0.95) x (NOx RACT limit in

1bs/MMBtu))J x (Estimated fuel use in MMBtu)} " 2000 pounds.

b. Acquire sufficient approved ERCs no later than the

first of each month to assure compliance for, at a

minimum, that calendar month. Excess ERCs from

previous months can be applied to subsequent

months. ERCs required shall be adjusted upwards

by 100% if ERCs are not in CL&P's possession prior

to use.

c. No later than the twentieth day of each month,

calculate ERCs used in the preceding calendar

month, as follows:

(1) For the boiler on each day, determine whether

the 24-hour average NOx emission rate is less

than the baseline emission rate or greater

than the NOx RACT limit.

(2) When the boiler has a daily NOx emission rate

(24-hour average) exceeding the NOx RACT

limit, calculate the amount of ERCs used, as

follows:

ERCs (tons) = {[(CEM-recorded NOx daily

average emission rate in lbs/MMBtu) -

((0.95) x (NOx RACT limit in 1bs/MMBtu))] x

(actual fuel use in MMBtu)) " 2000 pounds.

d. Maintain documentation to attest to the fact that

ERCs used during the ozone season were generated

during the ozone season. Generator certification

of this fact shall be sufficient.

e. After full program review, and if the Commissioner

deems it appropriate, the Commissioner may allow

the survival and use of these ERCs beyond April

30, 2003.

3. CL&P shall maintain records for the boiler showing

daily NOx mass emissions, and actual NOx emission rate

(24-hour average). CL&P shall also maintain records

showing a monthly total of all ERCs generated net of

the ten (10) percent environmental discount.

4. In requesting ERC approval, CL&P shall provide

documentation containing monthly operating reports of

actual fuel usage in MMBtu and actual heat input based

upon CEM-recorded data, daily actual NOx mass emissions

and NOx emission rates (24-hour average), number of

operating hours per day, and ERCs generated using the

baseline emission rate, net of the ten (10) percent

environmental discount.

5. No later than March 1 of every year after issuance of

this Trading Agreement and Order, CL&P shall include

with the Annual Emission Statement provided to the

Commissioner, a record of each sale or other transfer,

and use of any and all of the ERCs approved within and

subsequent to issuance of this Trading Agreement and

Order until all such ERCs have been used. CL&P shall

also include actual NOx emissions from the boiler, and

the amount of all ERCs used (inclUding approved ERCs

generated and/or purchased from other facilities),

generated and/or approved for the previous calendar

year. These reports will be on a form prescribed by

the Commissioner. This reporting may cease if a

central registry is approved by the Commissioner.

Should CL&P choose to discontinue the generation of

ERCs, CL&P will notify the Commissioner upon

discontinuance.
