air concentration to exceed 1 μg/m 3 , averaged over a 30−day period. [s. NR 446.03(1), Wis. Adm. Code]*

(2) MERCURY EMISSION LIMITS FOR NEW OR MODIFIED SOURCES.

(a) No person may commence construction or modification of a stationary source that results in an increase in annual allowa ble emissions of mercury of 10 pounds or

more from the new or modified source unless the person has obtained a permit und er ch. NR 406. The department may not issue a permit under ch. NR 406 for the

source unless the department finds that emissions of mercury will be controlled to a level which is best available control te chnology (BACT). 1.

(b) New or modified stationary sources that are subject to an emission limit for mercury required under section 111 or 112 of the Act (42 USC 7411 and 7412

respectively) are exempt from the requirements of this section.

(c) Except as provided in par. (b), this section applies to all new or modified sources for which an air permit application was submitted or should have been submitted to

the department under par. (a) on or after the first day of the calendar month following October 1, 2004.

[s. NR 446.03(2), Wis. Adm. Code]*

3. P rocedures for Determining Annual Mercury Emissions.

QUALITY ASSURANCE/QUALITY CONTROL PLAN (QAQCP)

1. INTRODUCTION

In accordance with 40 CFR 75, Appendix BV, MGE is require to develop and implement a quality assurance quality control (QA/QC) program for continuous emission

monitoring systems, excepted monitoring systems approved under appendix D and E of 40 CFR 75 and alternative monitoring syste ms under subpart E of 40 CFR subpart 75.

This document describes the QA / QC procedures for the excepted monitoring systems approved under appendix D, G and E that are employed to mea s ure emissions at the

Madison Gas and Electric Company's (MGE) Blount Generating Station. These moni toring systems measure emissions of sulfur dioxide (SO 2 ), nitrogen oxide (NO

x ), and carbon

dioxide (CO 2 ) from Boilers B 2 8 and B 2 9 which are required to comply with the Federal Acid Rain Program enacted under Title IV of the 1990 Clean Air Act Amendments.

1.1 Purpose

The primary purpose of this QA/QC Plan is to ensure that MGE maintains continuous compliance with the monitoring requirements of the Acid Rain Program (ARP) as

promulgated under Code of Federal Regulations (CFR) 40 Part 75. Appendix B of t hese regulations requires a written plan that describes in detail complete step

- by

- step

procedures and operations for each of the following activities: preventive maintenance, recordkeeping and reporting, maintenance records, instrument calib rations, and fuel

sampling. This document is intended to be used as a reference for the correct operation of emissions monitoring system for all responsible individuals including

technicians, environmental specialists and the Designated Representative.

In addition, this QA/QC Plan is intended to ensure that monitoring data from these systems can be used to satisfy State of Wisconsin compl iance demonstration regulatory

requirements promulgated under Wisconsin Administrative Code, Part NR 439. By maintaining complianc e with these regulatory programs, this QA/QC Plan will help

MGE maximize monitoring availability, accuracy, and data quality.

1.2 Scope

This QA/QC Plan implements the regulatory requirements for the QA / QC procedures as required under 40 CFR Part 75 , Ap pendix B

. A functioning QA/QC Plan requires

four major elements:

1. Specifications for acceptable system performance.

2. Periodic assessment of system performance.

3. Preventative procedures to limit excursions from these acceptable specifications.

4. Co rrective action procedures when the system exceeds acceptable specifications.

Federal regulations under 40 CFR Part 75 , Appendices D, G and E provide the specifications for acceptable performance. These regulations also specify the required

periodic asses sments of system performance in the form of routine checks and audits. Together with the regulatory requirements for system p erformance, this plan is

designed to function as a closed

- loop system where the quality of the monitoring data is periodically asse ssed and QC measures in the form of preventative maintenance or

corrective action are taken when specifications are exceeded. Each major activity associated with the continuous emission monitoring in this QA/QC Plan identifies the

individual responsible f or the activity, the procedures for completing the activity, and the acceptable conditions or specifications.

1.3 Implementation

The Senior Environmental Specialist has the primary responsibility for ensuring that the excepted monitoring systems approved under appendices D, G and E of 40 CFR 75

are operated and maintained in accordance with this QA/QC Plan. This will be accomplished through the continued evaluation of: ( 1) emissions data; (2) maintenance

records; and (3) quality assurance test re sults. Records related to the performance and maintenance of the monitoring system will be compiled and maintained by the Senior

Environmental Specialist. Additionally, the Senior Environmental Specialist will provide guidance pertaining corrective acti o n response and regulatory interpretation.ID 113004430, Permit No. 113004430

- P20

– Final Permit

66 The Senior Environmental Specialist has been authorized to act on behalf of the Designated Representative as an Agent who has the authority to submit monitoring

plan, QA and emissions data from the Emissions C ollection and Monitoring Plan System (ECMPS) Client Tool up to the EPA Host System and to retrieve data from

the EPA Host System. In accordance with the ECMPS reporting instructions for monitoring plans, quality assurance and certifi cation data, and emiss ions data, the

ECMPS evaluation tool will be used to determine the completeness and accuracy of the data. The Senior Environmental Special ist will exclusively use the ECMPS

Client Tool to electronically submit data to the EPA.

The Industrial Electrici an and Instrument Technician is responsible for performing periodic performance inspections, preventative and corrective main tenance, and

quality assurance tests.

1.4 Document Control

The QA/QC Plan is an important regulatory document. A s a result, strict document controls are required. The Senior Environmental Specialist is responsible for reviewing

the QA/QC Plan annually and for implementing revisions when they become necessary. As the QA/QC Plan is updated, the Senior Environmental S pecialist will distribute

the updated versions of the QA/QC Plan to appropriate personnel and departments and collect all obsolete versions.

A copy of the revised QA/QC Plan will be sent to the Wisconsin Department of Natural Resources for their review an d comment.

. PLANT DESCRIPTION

The Blount Generating Station is a natural gas

- fired electric utility steam generating plant. Boilers 8 (B28) and 9 (B29) are Babcock and Wilcox wall

- fired boilers constructed

in 1957 and 1961 respectively. Each bo iler supplies steam to an electric generator with generating capacities in excess of 25 MW(e). Both boilers are subject to t he Acid Rain

Program (ARP), the Clean Air Interstate Rule (CAIR) and the Greenhouse Gas Reporting Rule (GHG)

. 40 CFR 75.53 requires units subject to the ARP to maintain systems that

continuously monitor and report opacity and emissions of SO 2 , NO

x , C O 2 and other operating data. Boiler 8 and 9 meet the following 40 CFR 72.2 definitions of gas

- fired and

peaking units.

1

. Natural gas or other gaseous fuel (including coal

- derived gaseous fuel) for at least 90.0 percent of the unit’s average annual heat input during the previous three calendar

years and for at least 85.0 percent of the annual hea t input in each of those calendar years; and

2

. Fuel oil for the remaining heat input, if any.

Peaking unit means a unit that has:

1

. An average capacity factor no more than 10.0 percent during the previous three calendar years ; and

2

. A capacity factor of no more than 20.0 percent in each of those calendar years.

The gas

- fired boilers are exempt from monitoring opacity in accordance with 40 CFR 75.14(c). The gas

- fired and peaking unit qualificati ons are maintained in the

electronic monitoring plan found in the ECMPS Client Tool application.

3

. M ONITORING METHODOLOGY DESCRIPTION

Gas fired peaking units subject to the ARP may use alternate monitoring methodologies described in 40 CDR 75 to determine SO 2 , NO

x and CO 2 emissions, in lieu of a CEMS.

The alternate monitoring methodologies employed by MGE are described in detail in this section.

3.1 Appendix D and G Methodology

The procedures of 40 CFR 75 Appendix D are us ed to estima t e hourly SO 2 mass emissions and heat input from gas

- fired or oil

- fired units. The procedures of 40 CFR 75,

Appendix G are used to estimate CO 2 mass emissions from the combustion of fossil fuels.ID 113004430, Permit No. 113004430

- P20

– Final Permit

67 The alternate monitoring methodol ogies of Appendix D and G requires the continuous monitoring of fuel flow rate and periodic sampling of fuel. The monitoring system

measures gas flow rate in 100 standard cubic feet per hour. The gas flow rate is used to calculate SO 2 mass em issions and heat input rate. The system is comprised of a gas

flow monitoring system and a DAHS.

S O 2 emissions are determined by calculating the heat input of the natural gas an d using the sulfur content of the natural gas. CO 2 emissions are monitored using the methods

defined in 40 CFR 75, Appendix G. Heat input and a carbon

- based fuel factor are used to calculate CO 2 mass emissions using Equation G

- 4 in Appendix G. The following section

of the plan identifies the individual components whic h comprise the fuel flow monitoring system.

3.1.1 Fuel Flow Meters

MGE maintains a group of three identical Annubar natural gas fuel flow meters at the Blount Street Generating Station. MGE r otates the installation of t he meters

between boilers 8 and 9 to facilitate the removal of the meters for quality assurance accuracy testing. A summary of the mon itoring systems are provided in Table 1.

are not subject to calibration requirements of Appendix D. However, MGE contracts an independent laboratory to service and calibrate the meters annually.

MGE performs p eriodic sampling of the fuel to determine the sulfur content and gross calorific value (GCV) in accordance with 40 CFR 75, Ap pendix D. The d e tails

pertaining to fuel sampling are described in section 3 of this plan.

3.1.2 Pressure Transmitters

Multi variable transmitters are used to measure differential pressure, static pressure and process temperature from the primary fue l flow meters and calculate the fuel flow.

3.2 A PPENDIX E M ETHODOLOGY

The procedures of 40 CFR 75, Appendix E are used to estimate the average NO

x emission rate and hourly NO

x rate from the gas

- fired and oil

- fired peaking units.

Appendix E requires the hourly determination of the heat input to the unit, using a fuel flow rate measured by a certified Ap pendix D fuel flow meter, in conjunction with the GCV of

the fuel. An emission test must also be conducted at four different loads to develop a correlation curve of NO

x emission rate vs heat input rate. This curve is then used to estimate

the hourly NO

x emission rates. A summary of the NO

x monitoring systems are provided in Table 2 below.

68 3.2.1. Oxygen Monitor

Appendix E requires the continued monitoring of the boiler excess oxygen (O 2 ) levels. MGE uses an oxygen analyzer to measure the excess O 2 concentration of each

boiler. The two major components of the O 2 monitoring system are the analyzer and th e intelligent field transmitter.

3.3 Data Acquisition and Handling System

The DAHS consists of a datalogger and a Microsoft Windows

- based server. The datalogger serves as the interface between the process and fuel flow data and the system server.

Th e datalogger scans the input values once each second, digitizes the analog signals and scales the values to engineering units . The datalogger also calculates minute and hourly

averages and stores these values in an internal battery

- backed RAM. These value s are automatically retrieved by the server.

The server provides data polling and archiving, data editing, alarming, recordkeeping and report generating. It creates hour ly pollutant concentration, calculates emissions, and

creates electronic files of hou rly emissions.

3.4 Monitoring Plan

The monitoring plan describes the strategy for monitoring emissions. The monitoring plan defines the relationship between st acks and units, specifies locations at the facility from

which emissions are monitored and identifies monitoring systems. The monitoring plan also identifies operational characteristics and qualifications for altern ate monitoring

approaches.

The content the monitoring plan is defined by the EPA. The monitoring plan is a living document that mu st be continuously updated to reflect changes to the monitoring systems.

Changes to the monitoring plan are submitted to the EPA through the ECMPS Client Tool. The monitoring plan that resides with in the ECMPS Client Tool is the official

monitoring plan f or the facility.

75 7.2 Current NO

x Rate Test Results

In accordance with 40 CFR 75, Appendix E, MGE is required to include a c opy of all data and results from the most recent NO

x emission rate testing in the QAQC Plan.

The baseline NO

x versus heat input correlation curve was completed in December, 2014. A test to determine a new correlation curve is scheduled for December 2019. The

results of that test will be included in the QAQC Plan at that time.

7.3 Quality Ass u rance

- Quality Control Operating Parameter Ranges

40 CFR 75, Appendix E, requires continuous monitoring of the excess O 2 in the boilers. A NO

x versus heat in put correlation curve shall be re

- determined if the excess O 2 level at any heat input rate (or unit operating load) continuously exceeds by more than 2 percentage points the O 2 from the boiler excess O 2 level recorded at the same

operating heat input rate during the previous NO

x emission rate test for one or more successive operating periods totaling more than 16 unit operating hours. A summary of

the excess O2 measured in the boilers during the test is summarized in the following table.
