Glens Falls Community Advisory Panel Neil Hodgson Plant Manager 1

Agenda  Energy Star Award  NESHAP is Here! (National Emission Standards for Hazardous Air Pollutants)  Regional EIT’s (Engineers in Training)  Giving Back  Business Outlook Neil Hodgson 2 June 30 th 2015

Energy Star Award  Awarded by the U.S. Environmental Protection Agency  Voluntary participation  Top 25% in U.S. regarding energy performance  Recognizes Glens Falls energy management strategy Neil Hodgson 3 June 30 th 2015

NESHAP  National Emission Standards for Hazardous Air Pollutants  The most challenging rule facing the U.S. cement industry  Significantly lowers emissions limits of Hazardous Air Pollutants (HAPs)  Final revised rule released: February 2013  Technical revisions to rule due: June/July 2015  Compliance deadline: September 9, 2015 – Title V Air Permit modification to include NESHAP will be published and open for comment this summer Neil Hodgson 4 June 30 th 2015

NESHAP Limits  Plant is brownfield area source of Hazardous Air Pollutants (HAPs)  Required to meet existing source emissions standards  Exempt from compliance with HCl standard  EPA developed Portland Cement Maximum Achievable Control Technology Standards (or MACT) based on level of emissions achieved by best-performing similar sources Hazardous Air Pollutant PC MACT Standard Particulate Matter (PM) 0.07 lb/ton clinker Dioxins/Furans (D/F) 0.2 ng/dscm @ 7% O 2 Mercury 55 lb/MM tons clinker Total Hydrocarbons (THC) 24 ppmvd @ 7% O 2 (as propane) Hydrochloric Acid (HCl) 3 ppmvd @ 7% O 2 Neil Hodgson 5 June 30 th 2015

Extensive Monitoring to Ensure Compliance HAP Emissions Limit Emission Source Particulate Matter 0.07 lb/ton clinker Kiln Electrostatic (PM) Precipitator & Clinker Cooler Baghouse Dioxins/Furans (D/ 0.2 ng/dscm @ 7% O 2 Kiln Electrostatic F) Precipitator Mercury 55 lb/MM tons clinker Kiln Electrostatic Precipitator Total 24 ppmvd @ 7% O 2 (as Kiln Electrostatic Hydrocarbons propane) Precipitator (THC)  Also PM standard for outside clinker pile – Requires work practices, control measures to minimize particulate emitted from clinker piles staged outside for > 3 days Neil Hodgson 6 June 30 th 2015

NESHAP: What Changes?  Our plant already has low concentrations and emissions  For some HAPs, we do not need to change operations or raw materials  Largest emissions decrease will result from particulate matter and mercury Neil Hodgson 7 June 30 th 2015

NESHAP: Particulate Matter  Electrostatic Precipitator (ESP) – Structural and internal repairs – Revised controls  Clinker Cooler Baghouse and upstream equipment/ducting – Revised Baghouse Controls – Replaced tubesheets and style of bag  Modified Gas Conditioning Tower Controls (in progress) – Improved moisture control increases ESP performance Latest round of stack testing indicates plant will comply with new NESHAP limits – Continuous Parameter Monitoring Systems (CPMS) and annual stack tests to demonstrate compliance – 30 Day rolling average compliance criteria Neil Hodgson 8 June 30 th 2015

NESHAP: Baghouse / Precipitator Electrostatic Precipitator Baghouse (ESP ) Neil Hodgson 9 June 30 th 2015

Neil Hodgson 10 June 30 th 2015

NESHAP: Mercury  Shuttling system installed to remove kiln dust from Electrostatic Precipitator and Gas Conditioning Tower - Normally re-used in kiln - Now transported to finish mills and incorporated into cement  Only needed when plant is combusting coal  Decreases amount of mercury re-volatilized in gaseous emissions from kiln  Modified Gas Conditioning Tower Controls (in progress) – Improved temperature control increases mercury capture  Mercury Sorbent Trap System installed on Kiln Electrostatic Precipitator to monitor compliance – 30 Day rolling average compliance criteria Neil Hodgson 11 June 30 th 2015

Other Areas of Focus  Dioxins/Furans – No change in limits and monitoring – We continue to be in compliance  Total Hydrocarbons (THC) – Raw material monitoring and substitution used to comply with standard – Continuous Emissions Monitoring Systems installed on Kiln Electrostatic Precipitator to monitor compliance – Prior stack testing demonstrates plant will comply with revised standard Neil Hodgson 12 June 30 th 2015

EIT Program (Engineers in Training)  Identify and nurture talent – Develop ‘bench strength’ at the plant and within the Company  First program concludes in November – John Aylward, Glens Falls EIT, returns to the plant – Spent 4 months each at Union Bridge, Evansville, Mason City and Mitchell plants  North Region undertaking second program in 2016  Canada and West Regions are evaluating program Neil Hodgson 13 June 30 th 2015
