11:30 a.m. Update

On yesterday, Texas Brine advised that the tagging of Cavern 3 was at 4,094′ which is 9′ above last week’s tag. As information becomes available, it will be shared here. 

1:35 p.m. DPVE Informational Update

In response to concerns raised by members of the community in regard to the potential for subsidence possibly associated with the Dual Phase Vacuum Extraction (DPVE) program discussed at the most recent public meetings, Assumption Parish OEP Incident Command and the Office of Conservation have determined that additional analysis is warranted, given the sensitive nature of this program due to its location within a community. Though the DPVE process has not been associated with significant subsidence in the experience of consultants contracted by the Office of Conservation, the decision has been made, following technical discussions this week in which Texas Brine made reference preliminary results of its own subsidence calculations, to delay shallow DPVE system installation and testing in the community until subsidence impacts and the potential need for additional measures to ensure safe removal of gas from the shallow subsurface can be evaluated. This does not affect the requirement to continue the ongoing effort to maximize efficiency of gas removal from the Mississippi River Alluvial Aquifer.

To that end, Conservation is directing Texas Brine to provide a written report documenting the subsidence calculation results so that more detailed analysis can be performed , as well as the company’s plans regarding the installation and testing of the shallow DPVE system in the Bayou Corne community, on or before close of business on Friday, October 4.

1:45 p.m. Message from DOTD, non sinkhole related

There will be lane closures on LA 69 from LA 70 (intersection at Gator Corner) to the Iberville Parish Line starting on Saturday, September 28, 2013 thru Sunday, September 29, 2013.  The closures will be from 6:30 A.M. until 6:30 P.M. daily (weather permitting).   These closures are needed for crews to install new asphalt surfacing on LA 69.

These closures will allow vehicles 11’ wide or smaller to travel through the construction zone.

DOTD appreciates your patience and reminds you to please drive with caution through the construction site and be on the lookout for work crews and their equipment.

3:40 p.m. South Central Human Services Authority Services Available

Message from the South Central LA Human Services Authority

The South Central Louisiana Human Services Authority (SCLHSA) was created by Act 449 of the 2006 Regular Session of the Louisiana Legislature. This legislation merged the Offices of Mental Health, Addictive Disorders and Citizens with Developmental Disabilities into one integrated entity effective July 2, 2010. SCLHSA is responsible for overseeing and performing functions related to the care, training, treatment and education of individuals with addictive, mental and emotional disorders. The role of SCLHSA is to promote recovery and resiliency through the services and supports in the community that are preventative, accessible, comprehensive and dynamic. SCLHSA serves Terrebonne, Lafourche, St. Mary, Assumption, St. James, St. John the Baptist and St. Charles parishes in south Louisiana.

The combination of the cumulative stress from a displacement have shown that it is helpful to talk to someone in the recovery process. The SCLHSA can provide short-term, face-to-face outreach, education and support to help individuals and communities return to pre-disaster levels of emotional health.  Our behavioral health approach focuses on survivor’s strengths, resources, and resilience to overcome obstacles.  Our team of counselors would like to help you overcome whatever issues you are dealing with using supportive contact, referrals and resource linkage, and even presentations to your business, school, community, church, or organization. 

In the meantime, consider easing your stress in some of the following ways:

   – Stick to regular routines
   – Limit the use of caffeine/alcohol
   – Try to get some light exercise daily
   – Talk with a friend
   – Take time out each day for yourself
   – Do something relaxing and enjoyable
   – Don’t forget to laugh
   – Do fun activities with your children
   – Remind children that stress is normal
   – Talk with a SCLHSA Staff Member
   – Read a book
    – Most of all avoid dealing with your stress ALONE.  We want to help you, so please give us a call. 

There are many ways to benefit from our crisis counseling program.  The first step is making contact with  trained counselors who understand the challenges you are facing.
