Ulehawa Canal Update from C&C Environmental Services AND the State Department of Health

After hearing from numerous constituent who live near the canal, such as B. Fitzgerald, L. Corcoran, A. Lillis, and D. Kuamo`o,  Sen .Shimabukuro received the following responses from the City and State:

Received April 15, 2015 at 3:57pm from the C&C Department of Environmental Services:

The city’s Dept. of Environmental Services has received several complaints regarding odor at the Ulehawa Canal.  Here are excerpts from our staff and that of Dept. of Facility Maintenance [DFM], they oversee city streams.

From the standpoint of ENV and wastewater, we have sent out numerous crews the past few days with the following observances:

–  ENV sent a crew there last night to dye test the wastewater mainline. The test turned out negative (no signs of leakage from sewer pipes).

–  ENV sent in a closed-circuit television into the mainline pipe today in the area and conditions were normal.  ENV also did a site visit today with no signs of the dye in canal.

–  ENV inspected the Nanakuli Wastewater Pump Station Force Main and found no break or leakage, and we also checked the pressure and flow readings were all normal.

–  ENV’s Storm Water Quality Branch tells us that DFM is scheduled to open the Ulehawa Stream mouth starting April 20-May 6,2015.  This will remove the standing water and allow tidal waters to flush the channel.  DFM is also in the process of getting the permission of the Army Corps of Engineers to dredge the side channels.  DFM’s Road Department was on site today removing rubbish from canal.

Aloha Sen. Shimabukuro, 

Based on the news clip below, it appears that the odors are coming from stagnant water and trash that has accumulated in the canal.  The City is working on getting the approvals needed to clean out the canal. We don’t believe that there is anything DOH Waste Water Branch (WWB) could do to “expedite” this work, as you may have heard.

DOH Clean Water Branch (CWB) is waiting for Army Corp of Engineer (COE) determination in order to issue permit.  It may need 401 WQC permit for the clean-up
