SUPPLEMENTARY INFORMATION: The BNSF Railway Company has requested a
temporary deviation from the operating schedule of the swing span
railroad bridge across Boeuf Bayou, mile 10.2, in Amelia, St. Mary
Parish, Louisiana. The deviation was requested for the purpose of
removal and reinstallation of the east end reduction gear box, motor
shaft, and also to perform an alignment.
    In accordance with 33 CFR 117.5, the bridge currently opens on
signal for the passage of vessels. This deviation allows the swing span
of the bridge to remain in the closed-to-navigation position from 7
a.m. through 2 p.m. on September 18, 2014. At mean high water, the
bridge provides 6.6' of vertical clearance in the closed-to-navigation
position. However, the bridge will be able to open in the event of an
emergency.
    Notices will be published in the Eighth Coast Guard District Local
Notice to Mariners and will be broadcast via the Coast Guard Broadcast
Notice to Mariners System.
    Navigation at the site of the bridge consists mainly of tows with
barges and some recreational pleasure craft. Due to prior experience,
as well as coordination with waterway users, it has been determined
that this closure will not have a significant effect on these vessels.
An alternate route is available by using the GIWW, Morgan City to Port
Allen Alternate Route.
    In accordance with 33 CFR 117.35(e), the drawbridge must return to
its regular operating schedule immediately at the end of the effective
period of this temporary deviation. This deviation from the operating
regulations is authorized under 33 CFR 117.35.

    Dated: August 27, 2014.
David M. Frank,
Bridge Administrator, Eighth Coast Guard District.

AMENDMENT FOR THE ASSESSMENT OF END-USE

OCCUPATIONAL AND RESIDENTIAL OCCUPANT EXPOSURES TO

HCR-188C, A SAFE ALTERNATIVE HYDROCARBON

REFRIGERANT FOR WHITE GOODS SYSTEMS

1.0 INTRODUCTION

Alaska Industrial Hygiene Services (AIHS) has prepared this amendment to

Assessment of End-Use Occupational and Residential Occupant Exposures to
HCR-

188C, A Safe Alternative Hydrocarbon Refrigerant for White Goods Systems
(AIHS,

May 2007). This amendment was requested by A.S. Trust & Holdings to
clarify

additional information requested by the United States Environmental
Protection Agency

(EPA) under its Significant New Alternatives Program (SNAP).

This amendment specifically addresses potential exposures related to
window air

conditioning units and upright freezers as part of the previous white
goods assessment

that included household refrigerator units. Calculations contained in
this amendment

are based on charge rates of 124.74 and 121.9 grams of HCR-188C for
typical window

air conditioning units and 40 grams of HCR-188C for an upright freezer.
Charge rates

were provided to AIHS by A.S. Trust & Holding

October 31, 2007  Addendum

Charge and performance rates on the freezer was the same as the
refrigerator so the calculation was done at 25% of HCR-188C in the
upright freezer with same cubic feet dimension as the refrigerator.
