The document discusses site inspection requirements for construction projects under the California Construction General Permit. It covers the following key points:
1) Inspectors must be certified as Qualified SWPPP Practitioners and hold additional national certifications. They are responsible for conducting weekly, pre-rain, during-rain, post-rain, and quarterly inspections.
2) The volume of inspections is the same regardless of the project's assigned risk level, which is determined by a risk assessment considering impacts of runoff. However, higher risk levels require additional minimum BMPs.
3) Inspections aim to identify any issues that could cause a pollutant discharge, such as erosion, sediment deposition, or
The uses of automation in the drilling process are expanding and are typically resulting in improved drilling performance. However, many of these projects struggle in the initial stages, often trying to overcome a common set of hurdles. Many of these hurdles are not technical challenges, but instead are related to people issues and the methods for implementing the solutions. This presentation covers the basics of drilling automation and describes the problems and solutions that have been found to improve the startup success for drilling automation. IDEA TO TAKE AWAY - For automation to be successful, the key users, especially the driller, must be involved in every step of design and implementation.

The new Center for Sustainable Shale Development, a collective of both drilling companies and environmentalist groups, have proposed a new standards certification program. These 15 standards are the initial "first cut" at promoting more environmentally-friendly shale in the Marcellus Shale region. The intent is for drillers and pipeline companies to become certified by the CSSD. Without certification? Persona non grata.
Protecting your business from flood.
The effects of a flood on a business can be substantial, sustained and catastrophic. Thankfully, however, the costs and impact of a flood can be minimised by good planning, and an effective action plan can help your business recover with reduced impact on key customers and suppliers.
QBE have produced some guidance which can help prepare your business should the unthinkable happen.

5th International Disaster and Risk Conference IDRC 2014 Integrative Risk Management - The role of science, technology & practice 24-28 August 2014 in Davos, Switzerland
Intelligent water conservation and management techniques need to be adopted by the industry such that water can be optimally utilized. Now as per the recent forecasts and frequent occurrence of extreme events, the necessity of such management has become more significant. Based on this need, some start-up businesses can be established which can help to achieve the water conservation goals. Five such ideas are discussed in this presentation.

n the state of California, the
Construction General Permit require-
ments are similar to the Federal
Construction General Permit with a few
exceptions. All projects 1 acre or greater
are required to have a storm water pol-
lution prevention plan (SWPPP); must be
permitted through the storm water mul-
tiple application report tracking system;
and must receive a waste discharge iden-
tification (WDID) number.
The SWPPP must be prepared by
a Qualified SWPPP Developer (QSD),
including an initial risk assessment,
which uses a modified Revised Universal
Soil Loss Equation calculation to deter-
mine a project’s sediment risk in tons per
acre per year, and a receiving water risk,
which identifies if project site runoff will
run into a designated “Spawn, Cold or
Migratory” water body. The risk assess-
ment takes into consideration what is
coming off the site as well as what is
downstream of it, and assigns a Risk
Level 1, 2 or 3 designation—Risk Level
1 having the lowest potential impact.
Inspectors must understand the Risk
Levels, as there are different minimum
requirements for each; e.g., as the Risk
Level increases, additional minimum
BMPs are required.
Inspector Credentials
In the state of California, inspectors
are required to hold a QSP certificate
designating them as Qualified SWPPP
Practitioners, the qualifications for
which include 16 hours of California
Construction General Permit training fol-
lowed by an online state-approved exam.
They also are required to hold a national
certification from one of the following pro-
grams: CISEC, CESSWI, CPESC or CPSWQ.
A California licensed engineer, architect or
landscape designer also will meet the
underlying certification requirement.
Inspection Requirements
The volume of inspections—weekly,
pre-rain, post-rain, during rain after
24 hours and quarterly—are the same
regardless of Risk Levels.
Other requirements dictate that:
• Weekly inspections will be performed
by a QSP inspector, or someone ade-
quately trained and under the direct
supervision of a QSP.
• A pre-rain inspection (Risk Level 1)
must be performed by a QSP, or some-
one adequately trained and under the
direct supervision of a QSP. A rain
event action plan (REAP) is a more
sophisticated version of the pre-rain
inspection used for Risk Level 2 and 3
sites. A REAP must be performed
48 hours prior to a predicted rain
event that has 50%-plus probability
of precipitation, per the National
Oceanic & Atmospheric Agency.
• A post-rain inspection must occur
within 48 hours of the cessation of
rain by a QSP, or someone adequately
trained and under the direct supervi-
sion of a QSP.
• During-rain inspections must occur
every 24 hours during a rain event.
• Risk Level 1 sites need to have all outflow
points observed to ensure that BMPs are
working adequately.
• Risk Level 2 and 3 sites must have
turbidity and pH testing performed
on site at all outflow points once the
site has reached a qualifying rain
event (½ in. for California) during
normal business hours. Turbidity
testing requires a minimum of three
samples per outflow point, and the
nephelometric turbidity unit (ntu)
average must be below the numeric

action level (NAL) limit of 250 ntu, or
for pH, between 6.5 and 8.5. If the aver-
age of the turbidity samples exceeds
the NAL limit, action must be taken,
e.g., additional bag berms, wattles, etc.
• The requirements for pH sampling are
the same: three samples per outflow
point within two hours of reaching a
qualifying event of ½ in. during nor-
mal business hours. Using a pH scale
of 14, the pH NALs must be between
6.5 and 8.5. Although arithmetic aver-
aging for pH is not entirely accurate,
it still provides sufficient data to
understand a site’s pH value, as long
as the numbers averaged lay either
above or below 7. As an NAL example,
a high pH indicator—e.g., 8.7—might
indicate an uncovered concrete wash-
out that is now overflowing from the
rain event, and the action to be taken
to reduce the pH is to cover the wash-
out and retest.
• Quarterly inspections for non-storm
water discharges, authorized and
unauthorized, are primarily visual,
and are used to identify non-storm
water discharges that may have
caused erosion and sediment issues,
as well as flows through materi-
als storage areas that might carry
pollutants to a storm drain or
water body.

site inspection
sites on any given day. Their schedules are
somewhat fixed, as they are required to
visit each project site at least once a week.
Inspectors dress in the standard safety gear
required on active construction sites, which
includes long pants, long-sleeve shirts,
safety shoes, safety vests, hardhats, safety
glasses and gloves, if needed. Inspectors
are trained to drive around a project’s outer
perimeter when possible to ensure the
site’s external integrity. They then enter
the site, driving slowly, and check in with
site management. Key items checked in the
office include the posted notice of intent/
WDID number, and a review of the SWPPP
and inspection documentation and filing
system. The site map reflecting the BMP
deployment is reviewed to ensure that it
reflects the status of BMPs that day, as
well as updates with dates and initials.
The inspector will ensure that the daily
weather forecast is printed and filed in the
state-required format. Part of an inspec-
tor’s responsibility is to understand current
site conditions and construction activity
through discussion with the superinten-
dent or project manager.
The inspector then will walk or drive
around the site, either alone or with a
designated individual. Key issues to be
observed include indications of erosion,
sediment deposition and waste manage-
ment issues. The two biggest red flags
for any site are tracking or track-out
issues and housekeeping. The inspec-
tor will check BMPs to ensure that they
meet minimum requirements based on
that Risk Level. Indications of erosion,
sediment or compromised BMPs will be
photographed to aid in communication
with site management. Urgent issues
will be verbally communicated with site
management prior to leaving the site. The
final step in the weekly inspection pro-
cess is the generation of formal written
report with site photos. All other inspec-
tions are weather driven; pre- and post-
rain inspections can be combined with
the weekly inspections if timed correctly.
In Summary
A well-trained inspector working for
an owner, general contractor or agency
has one primary responsibility: to iden-
tify potential problems that might cause
a pollutant discharge into a storm drain
or receiving water. Communication,
training and followup are the keys to
effective compliance. If we keep that in
mind and realize that everything else
is designed to support that goal, we can
effectively impact water quality, and
will not have as many contaminated
water issues. SWS
