NOTE - THE NOTED DISAPPROVED ITEMS MAY NOT CONSTITUTE A COMPLETE LIST OF VIOLATIONS. THE DESIGNER IS TO CONDUCT A COMPLETE RE-REVIEW OF THE PLANS FOR ADDITIONAL VIOLATIONS OF THE STANDARD COMMENTS AND INCORRECT INFORMATION PRIOR TO RESUBMITTING. System plans must be picked up within 30 days. All system plans left longer than 30 days will be discarded as abandoned.

| Disapproved | CHEMICAL INVENTORY, AS DECLARED
*** Not declared on plans or attached to plans.
Note: The PPRBD code analysis form shows that "No" hazardous materials are part of the scope of work
for this project.
The work includes installing a roof over a Flammable Class I liquid storage tank that is in an existing partially vaulted enclosure. Vault requirements are set forth IFC 2003, Chapter 34.
Attention to ventilation, monitoring and detection of liquid and vapors is required.
Note: Phone conversation with CSU declares that the tank is 1000 gallons methyl mercaptan Scentinal product. See additional product info on MSDS and in comments herewith.

FIRE CLASSIFICATION:
OSHA Classification (29 CFR 1910.1200): Flammable liquid.
NFPA RATINGS: Health: 1 Flammability: 3 Reactivity: 0
FLAMMABLE PROPERTIES:
Flashpoint: < -18 °C (-0.4°F) Estimated
Autoignition: NDA
Flammability (Explosive) Limits (% by volume in air): Lower: NDA Upper: NDA
General Storage Information: DO NOT USE OR STORE near heat, sparks or open flames. USE AND STORE ONLY IN WELL VENTILATED AREA. Keep container closed when not in use. Container is not designed to contain pressure. Do not use pressure to empty container or it may rupture with explosive force. Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other sources of ignition.
***
A Fire Code and fire and safety analyses shall be completed to identify compliance with the IFC 2003, Chapter 34 and 27. SEE EMAIL AND REFERENCED CODE SECTIONS.
The Plans do not declare or identify the chemical storage, quantities, hazards and requirements for a flammable, Class I liquid, vaulted tank enclosure. Due to the absence of this information a meeting is setup to discuss the applicable code and standards requirements. MSDS have been subsequently supplied by CSU. |
| E-Mail | Hello Steve, Jon, and Marilynn,
I spoke with Marilyn this morning and she would like us to conference call or discuss the mercaptan plans on Monday, November 9. I#m available most anytime time by phone. And, if you like, we can meet at the Fire Dept. Complex (FDC) or Regional Building Dept. Meanwhile, I#m attaching chemical, physical and other environmental, health and safety info regarding mercaptan.
Code requires monitoring and detection for liquid and vapor releases and to provide adequate ventilation to mitigate any flammable atmosphere. As a Class I flammable liquid (1,000 gallon tank), the following IFC 2003 code requirements apply:
Chapter 34, Flammable and Combustible Liquids; Section 3404.2.8 Vaults; 3404.2.8.1 through 3404.2.8.18
Ventilation, detection and monitoring is found in 3404.2.8.8 through 3404.2.8.11.

| E-Mail | Kay,
Attached are the appropriate technical data and material data sheets for the gas odorant used and stored at the 5 city gate meter stations. Chemical properties my be similar but we do use Methyl Mercaptan. We use a Tertiary Butyl Mercaptan/Methyl Ethyl Sulfide blend produced by Chevron Phillips Speciality Chemical and branded as Scentinel S-20 Natural Gas Odorant.
I will plan on attending the conference call on Monday to address CSFD and Springs Utilities concerns.
