Construction Self-Audit Compliance Monitoring

Combined Review Results

Figure D-1 and Table D-3 present a summary of the total numbers of Independent Quality Assurance (IQA) review findings. The total numbers are further divided into totals of administrative and field BMP findings. Some districts were visited more than others because of the number of projects and the project ranking process. Items of note in the following table are as follows:

• 201 IQA Reviews were conducted in the reporting period • Construction projects were visited in all districts • Very few administrative findings were noted during the IQA review. • Total findings (Administrative and Field BMPs) averaged approximately 12 per

IQA review which is an increase from approximately 9 BMP findings per IQA review during the 2018-2019 reporting period.

Administrative Findings

Table D-4 and Figure D-2 present the summary of administrative findings separated into several categories. The definitions of each category are as follows:

• Plans and Permits: Whether the SWPPP is located on site and was it developed by a Qualified Stormwater Developer (QSD).

• Training: Whether the Water Pollution Control Manager (WPCM) is certified as a QSD (or Qualified Stormwater Practitioner (QSP) for Water Pollution Control Program (WPCP) construction projects) and is the contractor conducting regular training with adequate documentation.

• SMARTS: Whether appropriate annual reporting is uploaded into SMARTS. • Active Treatment System (ATS): For construction projects that employ an ATS,

are all the required procedures of the ATS followed. • Construction Site Monitoring: Whether all the site monitoring has been

completed, and if an NAL has been exceeded, has a report been developed and reported to the SWRCB.

• Tahoe Permit: Questions regarding the following: o 1) For projects within the Tahoe Permit, has a Restoration Monitoring Plan

been developed? o 2) Are there waste prohibition exemptions on file (100 year floodplain)? o 3) Have all analytical information been uploaded into SMARTS within 5

Items of note in the following table are as follows:

• Administrative findings were encountered during 85 IQA Reviews (42.3%) of the construction projects (multiple Administrative findings were encountered during 33 IQA Reviews).

• No findings were encountered for administrative categories related to the Tahoe Permit or ATS.


• Findings in the Training category were encountered most frequently of all administrative categories.

Field BMP Findings

Table D-5 and Figure D-3 presents a summary of the field BMP findings separated into the six standard field BMP categories as follows:

• Soil Stabilization: Includes temporary cover of DSAs, temporary run-on and run-through control.


• Sediment Control: Includes temporary perimeter control, temporary face of slope controls, temporary check dams and temporary drain inlet protection.

• Tracking Control: Includes stabilized construction entrances and construction roadways.

• Wind Erosion Control: Includes the control of dust throughout the construction site.

• Non-Stormwater Control: Includes dewatering, paving and sawcutting operations, equipment cleaning, fueling, and maintenance, pile driving operations, concrete finishing activities, and working near and over water.

• Materials and Waste Management Control: Includes material storage and use, stockpile management, spill prevention and control, and waste management including solid, hazardous, contaminated soil, concrete, sanitary, and liquid wastes.

Items of note in the following table are as follows:

• The field BMP category of Materials and Waste Management Control constituted 50.3% of the total findings.

• The field BMP category of Sediment Control constituted 28.1% of the total findings.

• The remaining, combined field BMP categories of Soil Stabilization, Tracking Control, Wind Erosion Control, and Non-Stormwater Control constituted 21.5% of the total findings.

BMP Findings of Field BMP Types and Trends

Table D-6 presents a summary of the field BMP findings by field BMP type and specific IQA reviewer observations.

Each field BMP type has standards that regulate the correct application (e.g., is the BMP implemented or implemented as intended?), the correct installation or placement, utilizing the correct materials, and the proper maintenance. The following table indicates the number of findings for each field BMP type that did not meet one of these listed standards.
