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. 8161

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 Montville Station at 74 Lathrop Road in Montville,

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

operates Montville Station Unit 5, an 82 megawatt

tangentially-fired boiler on No. 6 fuel oil and/or

natural gas, Connecticut Registration Number 107-0017,

{"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 1995, prior to modifications of the

boiler's burner, combustion controls, operating

conditions and based on CEM data certified to 40 Code

of Federal RegUlations Part 75, the average annual NOx

emission rate for Montville Station Unit 5 was 0.245

pounds per million British thermal units ("lbs/MMBtu")

of heat input when operating on No. 6 fuel oil and

0.211 Ibs/MMBtu of heat input when operating on natural

gas. 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 0.25

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

oil and 0.20 Ibs/MMBtu of heat input when operating on

natural gas.

4. In 1995, 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 emissions rates. Such

modifications 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 0.25

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

oil and 0.20 Ibs/MMBtu of heat input when operating on

natural gas for use as emission reduction credits

("ERCs") .

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.

2 Date:

When properly documented by CL&P, and approved by the

Commissioner, the emission reductions identified above,

and as computed in accordance with the terms of this

Trading Agreement and Order, will conform to the

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

Specifically, the reductions will be:

Real 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.

Quantifiable 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 is 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, 55 ERCs were created by the boiler between

November 1, 1996 and September 30, 1997 (37 during the

ozone season and 18 during the non-ozone season). Qf

the 37 ozone season ERCs, 18 early emission reduction

credits were created below the standards prescribed in

Section 22a-174-22a of the RegUlations (the NOx Budget

Program) during 1997 by the boiler and shall be

converted into allowances.

benefit to the environment, leaving 31 ERCs available

for use (15 ozone season and 16 non-ozone season).

B. The Commissioner, in accordance with the provisions of this

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 31 tons of NOx ERCs

referenced in paragraph A.9. of this Trading Agreement and

Order (15 during the ozone season and 16 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 I, 2003,

whichever occurs first.

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

Sections 22a-6, 22a-171, 22a-174, 22a-176, and 22a-177 of

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

4 Date:

ERe generation. For purposes of generating ERCs from

the boiler at the facility, CL&P shall use 0.25

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

oil and 0.20 Ibs/MMBtu of heat input when operating on

natural gas as the baseline emission rates for the

boiler, or the proportioned baseline emission rate set

forth in footnote 2 of paragraph C.10. of this Trading

Agreement and Order, when simUltaneously operating on

more than one fuel. CL&P shall use the above

referenced baseline emission rate(s) when calculating

the proportioned baseline emission rate. When

calculating ERCs, CL&P shall use the lower of CEMrecorded 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.

2. ERC 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 1bs/MMBtu - ((0.95) x {NOx RACT limit or

proportioned emission rate calculated pursuant to

Section 22a-174-22(fl (21 (AI of the Regulations in

lbs/MMBtu))] 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&F'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:

5 Date:

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 RAeT limit.

Trading Agreement

and Order No. 8161

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

(24-hour average) exceeding the NOx RAeT

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 or proportioned

emission rate calculated pursuant to Section

22a-174-22 (f) (2) (A) of the Regulations in

lbs/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 rates

(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(s), or the proportioned baseline

emission rate, net of the ten (10) percent

environmental discount.

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

Initials: 6 Date:

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.

6. In order to consider CEM-recorded NOx emission rates

valid for ERC approval, all NOx and CO2 /02 CEMs must

comply with 40 Code of Federal Regulations Part 75.

7. CL&P shall retain records and supporting documentation

as described in this Trading Agreement and Order for a

minimum of five years, commencing on the date such

records were created. CL&P shall provide the records

specified above to the Commissioner within thirty (30)

days of receipt of a written request from the

Commissioner.

8. Upon sufficient documentation that CL&P has met the

requirements of paragraphs C.1., C.3, C.4., and C.10.,

of this Trading Agreement and Order, the Commissioner

may provide written approval of ERCs created by CL&P

retrospectively, in addition to those approved in

paragraph B. of this Trading Agreement and Order.

Requests for approval of all subsequent ERCs created

shall be submitted in writing to the Commissioner.

Approved ERCs created by CL&P may be held or

transferred to other persons. Such ERCs shall remain

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

whichever occurs first.

9. Should CL&P choose to generate additional

compiled

10. When the boiler has daily NOx emissions below the

applicable baseline emission rate(s), or the

proportioned baseline emission rate, CL&P shall

calculate the amount of ERCs generated as follows:

ERCs (tons) = {[Total heat input! of all fuels in MMBtu

x ((proportioned baseline emission rate 2 ) - (the CEMrecorded NOx emission rate 3 ))] + 2000 Ibs/tonJ x

(0.90) .'

I Heat input shall be calculated using the lower of

CEM-recorded data or actual fuel usage data in MMBtu

per unit of fuel combusted.

2 This rate shall be calculated by l}multiplying the

heat input of each fuel combusted by the baseline

emission rate(s) for such fuel; 2) summing those

products; and 3) dividing the sum by the total heat

input. If the boiler is operating exclusively on one

fuel, CL&P may replace the proportioned baseline

emission rate with the applicable baseline emission

rate, for that fuel.

3 This rate shall be calculated pursuant to the

methodology described in 40 Code of Federal Regulations

Part 75.

4 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.

11. As used in this Trading Agreement and Order,

"Commissioner" means the Commissioner of Environmental

Protection or an agent of the Commissioner. "Ozone
