Facility Specific Temporary Permit Conditions 

I. Facility Description of Operations

Public Service of New Hampshire - Merrimack Station is a fossil fuel-fired electricity generating 

facility, owned and operated by Public Service of New Hampshire (PSNH), a subsidiary of Northeast 

Utilities. The facility is comprised of two utility boilers, two combustion turbines operating as load 

shaving units, an emergency generator, an emergency boiler, and coal handling systems including 

primary and secondary coal crushers, coal piles, coal conveyor systems, and coal unloading from 

railcars. The facility operations also include various activities that are classified as insignificant or 

exempt activities. 

The two utility boilers (MK1 and MK2) primarily burn bituminous coal, the two combustion 

turbines primarily burn No. 1 fuel oil or JP-4, the emergency generator burns No. 2 fuel oil or diesel

fuel, and the emergency boiler burns No. 2 fuel oil or diesel fuel. PSNH – Merrimack Station ignites 

the utility boilers with No. 2 fuel oil. 

Each boiler stack is equipped with continuous emissions monitoring systems (CEMS) and a 

continuous opacity monitoring system (COMS). PSNH – Merrimack Station has installed control 

equipment and implemented operational changes to reduce emissions, including trials of low sulfur 

coals to control sulfur dioxide (SO2) emissions, selective catalytic reduction (SCR) systems to 

control nitrogen oxide (NOx) emissions, and electrostatic precipitators (ESP) to control particulate 

matter (PM) emissions. PSNH has also initiated mercury reduction trials including carbon injection 

and the use of low mercury coals. 

PSNH – Merrimack Station operates a fly ash reinjection system in each of the two Boilers. 

II. Project Description

The Owner has filed a Temporary Permit application requesting to install a wet, limestone-based flue 

gas desulphurization (FGD) system to control mercury emissions from Electric Generating Units 

MK1 and MK2. The FGD system will also provide a co-benefit by removing sulfur dioxide 

emissions. The application was filed in accordance with RSA 125-O:13,I, which requires this 

facility to file an initial permit application by June 8, 2007. This permit establishes limits on 

mercury and sulfur dioxide emissions based on the requirements of RSA 125-O:13 and 40 CFR 

51.308, respectively. This permit also contains applicable monitoring, performance testing, 

recordkeeping and reporting requirements for the purpose of ensuring that the facility can comply 

with the requirements of RSA 125-O:13 and 40 CFR 51.308. 

Once the FGD system is constructed and operational, initial stack testing on MK1 and MK2 will be 

used to (1) determine whether the facility complies with the applicable mercury and sulfur dioxide 

limits; and (2) to establish any necessary operating parameters to ensure that the mercury and sulfur 

dioxide limits will be met on an ongoing basis. Periodic stack testing and/or continuous emission 

monitors will be used to verify that the parameters used to monitor and control mercury and sulfur 

dioxide emissions continue to be valid.
