Inspection Summary:
We began our sample point inspections at SDO-ALT on the North side of the facility. ADO-ALT is sampled from the concrete
flume that carries stormwater from offsite. SDO-ALT doesn't need to be sampled because it is stormwater flowing from offsite
and doesn't represent stormwater from anything on the flowserve facility site. If there were outfalls that have trouble with high
benchmark readings it would be valuable data to determine if any offsite flow is a contributor to the exceedances, but that's
not the case here.
SDO-001 is a approximaetly 24inch RCP pipe and is a valid sample point
SDO-005 is the outfall that is in question and is the outfall I added on my last inspection. SDO-005 is a valid sample point
as it discharges concentrated flow from products (Metal valve components)staged on site. The consultant believed that due
to the possibility that SDO-005 may join SDO-002 after flowing through the woods, SDO-002 could be a representative
outfall. Since he requested that SDP-005 be removed from the sampling requirements because it wasn't concentrated flow,
that was denied. SDO-005 is concentrated flow when it leaves the production area at a curb outlet into a wooded area
SDO-002 is RCP pipe approximately 10inches in diameter and is a valid sample point.
SDO-004 outlets to the creek at just above water level and is a danger to reach. Therefore the sample should be taken at
either the last(or lowest)drop inlet of two on the SW side of the facility, or by sampling both drop inlets.If the cloth BMP in
the last(or lower)inlet is removed, both inlets can be sampled by sampling the pipe at the bottom of that last drop inlet,
therefore sampling stormwater from both inlets.The alternative is to sample both inlets above the cloth BMP at the grate. (if
that option is chosen an additional sample point most be added at the upper drop inlet)
SDO-003 is a valid sample point
To summarize the findings, the request for removal of SDO-005 is denied. There is an option for a request for Representative
outfall status (ROS)for other outfalls that can be requested.
