Hazardous Materials Survey Report – Blackburn OPUD South Yuba Sewer 3 Executive Summary
The purpose of the inspection was to determine the lead and chromium content associated with the yellow traffic striping on a small stretch of McGowan Parkway Road located at 1976 McGowan Parkway, Olivehurst, California for an upcoming construction project that involves the removal of the yellow paint striping.

This is a summary of the report. The report must be read in its entirety, and the reader must review all the detailed information provided in the body of the report prior to making any interpretations, or conclusions pertaining to the information. Any conclusions made by the reader about the information provided in the body of this report which are contradictory or not included in this report are the responsibility of the reader.

Introduction
This report presents results of a limited lead and chromium survey performed by Entek Consulting Group (Entek) which included the yellow paint striping located north of 1976 McGowan Parkway Road in Olivehurst, California. Entek understands that removal of the yellow paint striping on McGowan Parkway is anticipated to occur as part of future construction plans for the upcoming alignment project.

The survey was conducted by Mr. Karl Suarez on June 16, 2021. Mr. Suarez is a State of California Department of Public Health (CDPH) Certified Lead Sampling Technician under the direct supervision of Mr. Andy Roed who is a CDPH Lead Inspector/Assessor.

This report was prepared for Ms. Nicole Hart, Senior Project Manager with Blackburn Consulting.

Lead & Chromium
On June 16, 2021, Entek investigated the existing paint on McGowan Parkway Road in an effort to determine if lead and chromium were present in these materials.

The yellow paint striping on McGowan Parkway Road was sent to ALS Environmental an AIHA accredited lab for analysis. Based on the laboratory analysis, both chromium and lead were determined not to be present above the laboratory’s detectable limits of <9.9 ppm for lead and <4.0 ppm for chromium.

Based on these results, any work impacting the yellow striping paint will not require any special training or work practices related to lead and chromium as both concentrations were below their respective laboratory limits.

Survey Area Description
One bulk sample of the road striping paint was collected directly from the paint on an asphaltic substrate in the middle of the road within the left-turn only lane located north of 1976 McGowan Parkway Road. McGowan Parkway Road is a medium traffic road with three lanes. One lane running eastbound, one lane running westbound, and one middle left-turn only lane in the middle of the two with businesses on both sides. 2443

ENTEK
Hazardous Materials Survey Report – Blackburn OPUD South Yuba Sewer 4 Lead Sampling Results
One (1) bulk sample of the paint on the asphaltic road from McGowan Parkway Road was collected from the middle of the road and submitted to ALS Laboratory in Salt Lake City Utah, which is an accredited laboratory governed by the American Industrial Hygiene Association (AIHA) to perform this analysis. This sample was analyzed by a modified NIOSH 7300 method for bulk sampling. Results of the analysis are listed in the following table:

Paints/Coatings/ Materials Determined NOT TO Contain Lead Paint/Coating Color Lead
Content (ppm)
Component/Location
Yellow Paint <4.0 Yellow Striping Paint on Asphalt Collected from McGowan Parkway Road
Paints determined “NOT TO” contain lead for the purposes of this report are those samples which when analyzed did not indicate lead to be present at or above the limit of detection for the analysis method used. This limit of detection was 50 parts per million (ppm). As a result, any paints shown “NOT TO” contain lead will not require any special training or work practices related to lead when impacted and Cal/OSHA’s CCR, Title 8 Section 1532.1 (§1532.1) Lead in Construction Safety Orders will not apply.

Chromium Sampling Results
One (1) bulk sample of the paint on the asphaltic road from McGowan Parkway Road was collected from the middle of the road and submitted to ALS Laboratory in Salt Lake City Utah, which is an accredited laboratory governed by the American Industrial Hygiene Association (AIHA) to perform this analysis. This sample was analyzed by a modified NIOSH 7300 method for bulk sampling. Results of the analysis are listed in the following tables:

Paints/Coatings/ Materials Determined NOT TO Contain Chromium Paint/Coating Color Chromium
Content (ppm)
Component/Location
Yellow Paint <9.9 Yellow Striping Paint on Asphalt Collected from McGowan Parkway Road
The analysis of the paint determined that chromium within the paint was below the laboratory’s detection limit of 9.9 ppm. Cal/OSHA has not established a concentration of chromium in a product where their regulations apply, therefore since chromium was analyzed below the laboratory’s detection limit, CCR, Title 8 Section 1532.2 (§1532.2) Chromium does not apply.

Although the Cal/OSHA’s Construction Safety Orders for both Lead and Chromium does not apply to the upcoming project, Entek recommends, that general dust controls be utilized during the removal of the paint striping on McGowan Parkway Road. - l

ENTEK
Hazardous Materials Survey Report – Blackburn OPUD South Yuba Sewer 5 Additionally, construction dust or debris leading to or near storm drains, waterways, and other sources of water during removal of the yellow paint striping should be considered during future construction activities.

Limitations
Entek surveyed only the yellow striping paint expected to be impacted by the future construction work on McGowan Parkway Road. As a result, the information provided in this inspection report may not be used to extend the inspection results to areas not included in this report without additional review and sampling as necessary.

Entek’s policy is to retain a full copy of these written documents for three (3) years once the file is closed. At the end of the 3-year period the written files will be destroyed without further notice. It is suggested copies of the file(s) are maintained as per Blackburn Consulting’s policy.

Entek will be providing only this electronic copy of the report and its attachments for your use. However, if you would like a hard copy of this report please do not hesitate to ask.

Entek will be happy to mail the report upon receipt of your request.

Subject: RE: Mix up on COC
Hi Mike,
The samples listed at 11:15 are (Olivehurst) 2A, 28, 2C and the samples listed at 11:30 are (Olivehurst) lA, 18, and lC.

The jars should be correct, I believe this was just an error on the COC.

Thanks for catching this.

HI Luke,
Left you a VM just now, we have sample ID names on COC listed as (Olivehurst) lA, 1B,lC and Jars that are marked as (Olivehurst) 2A, 2B,2C, the time listed on COC and Jars do match (11:15). Thanks Mike Jaroudi
