INTRODUCTION

\ This document presents the Mine Waste Piles Engineering Evaluation and Cost Analysis

^- Study (EE/CA) Work Plan for 38 mine waste piles located in residential areas of the

California Gulch Site (Site), Leadville, Colorado. This work plan follows the guidance

L presented in the Draft Engineering Evaluation/Cost Analysis Guidance for Non-Time- Critical Removal Actions (EPA 1988a). The purpose of this work plan is to present the

1 scope of the investigation and the field and laboratory procedures for the collection of

data and evaluation of removal/remedial alternatives, if necessary, for 38 mine waste

] piles. As described in Section 1.1 below, five of the 38 piles belong to Mineral Group 1

(no minerals of concern), and three of the piles are stockpiles of construction materials, I as identified in the Final Mine Waste Piles Remedial Investigation (RI) Report (Asarco

^- 1994a). As a confirmation that the Mineral Group 1 piles pose no concern, one pile

from this group will be investigated as part of this EE/CA. Therefore, a total of 31 piles

L will be investigated.

1 The initial objective of the Mine Waste Piles EE/CA is to evaluate if the lead content

of the surficial materials (0-2") and near-surface materials (2-24") in the 31 mine waste

. piles located within residential Leadville exceeds 2,000 parts per million (ppm). Piles

whose average concentration of the surface and near-surface materials exceeds the

; 2,000 ppm threshold may then be tested for engineering and geochemical characteristics

^ such as material classification, compaction characteristics, acid rock drainage (ARD)

potential and teachability. The additional geochemical and engineering characterization

L work, if necessary, will be used to assess reclamation requirements, disposal

requirements, and possible alternative uses for these materials.

i

i

w» Piles with average lead contents of 2,000 ppm or less will be lef t in place until their final

; disposition is resolved under the Record of Decision (ROD) for the Site. Alternatively,

these piles may be removed and used elsewhere on-site as construction materials.

^ 1.1 DESCRIPTION OF MINE WASTE PILES

Thirty-eight numbered mine waste piles have been identified as a potential concern in

"" the Work Area Management Plan (Asarco 1994b) (Figure 1-1). Table 1-1 presents a

summary of the characteristics of these piles. These piles have been visually evaluated

*— for mineralogy as part of the reconnaissance of mine waste piles in the populated area

r~ as reported in the Final Mine Waste Piles Remedial Investigation (RI) Report (Asarco

L 1994a). Pile No. 16, identified on Table 1-1, was investigated in more detail as part of

the RI field program. Based on the reconnaissance, each pile was assigned a mineral

^ group number as described in Section 2.2.2 of the Final Mine Waste Piles RI Report

(Asarco 1994a). The mineral groups are as follows:

Mineral Group 1 - No minerals of concern

Mineral Group 2 - Manganese and carbonate minerals

*•• Mineral Group 3 - Minor sulfides, no galena

: Mineral Group 4 - Abundant sulfides , no galena

L. Mineral Group 5 - Abundant sulfides and visible galena

^ For the purposes of this EE/CA, the five mineralogy classes have been combined into

three categories as shown in Table 1-2. Category 1 mine waste piles (previous mineral

i group 1) were found during the Mine Waste Piles RI to contain no minerals of concern.

Category 1 includes pile nos. 11, 35, 107, 332, and 334. One pile from this group will be

i investigated as part of this EE/CA. Pile No. 35 will be sampled unless access cannot

*"" be obtained. In addition, three piles, nos. 330,541, and 542, were identified as stockpiles

of construction materials (sand, gravel) during the reconnaissance and require no

L- additional evaluation. Therefore, 31 mine waste piles will be investigated under the

work plan. Category 2 mine waste piles (previous mineral group 2) contain manganese

i

w

 and carbonate minerals, and may contain sufficien t minerals of concern to require some

remedial action. These piles will be sampled and tested to further characterize the

: materials and will be reclassified as Category 1 or 3 based on the material test results

k»

for lead. Category 3 mine waste piles (previous mineral groups 3, 4, and 5) contain

variable amounts of visible sulfide minerals and galena, and may potentially require

some remedial action. These piles will be sampled and tested as necessary to further

, characterize the materials.

I For those piles which exceed 2,000 ppm lead as an average of the near-surface and

surficial material, remedial options will be identified and presented as part of the

; EE/CA. In addition, these piles may undergo additional testing to assess reclamation

requirements, disposal requirements, and possible 'alternative uses for these materials

" elsewhere at the Site.

f

 1.2 PREVIOUS INVESTIGATIONS L

Asarco completed a remedial investigation on the 164 mine waste piles located near the

i populated area. Initially, the field reconnaissance was conducted to segregate the piles

into five mineralogy groups as described above. Eleven piles were then selected to be

(

 representative of mineral groups 2-5 and investigated as described in the Final Mine

*"" Waste Piles RI Report (Asarco 1994a).

u

 Samples were collected of surface and subsurface mine waste and the underlying

foundation soils and analyzed for total metals, nutrients, Method 1312 leaching potential, L and physical properties. In addition, four monitoring wells were installed (two each in

Stray Horse Gulch and Little Stray Horse Gulch) and surface water samples collected

at the mouth of Stray Horse Gulch and in Starr Ditch.

1 J CULTURAL RESOURCES

The Leadville area has been classified as a National Historic Landmark. Therefore the

identification and evaluation of the p

must be conducted for the EE/CA.

I

*" identification and evaluation of the potential effect s of remediation of historic properties

Consideration of Cultural Resources for all CERCLA activities at California Gulch is

required by the National Historic Preservation Act. The two primary documents that

will be used to implement the requirements of the National Historic Preservation Act

at the Site are: 1) the Programmatic Agreement between EPA, the State Historic

Preservation Officer (SHPO), and the Advisory Council; and, 2) the Cultural and

Historic Resources Identification and Evaluation (ID&E) Plan prepared by Asarco

(1994c).

22909N-223Z7/R43.1 07-21-94(4:19pm)/RIT/31 1-3
Woodward-Clyde L

The Programmatic Agreement (PA) requires that remedial actions, if necessary, be

conducted in accordance with certain stipulations in order for EPA to satisfy Section 106

i of the Historic Preservation Act. The stipulations provide for: an identification and

evaluation process for assessing effect s on and managing historic properties; development

"~ of a plan for management of historic properties; discovery of historic properties during

*- remedial actions, involvement of interested persons (i.e., public); adherence to standards

and guidance; and professional qualifications for this work. L The ID&E Plan has been developed by Foothills Engineering for Asarco. All parties

i conducting identification and evaluations of historic properties will be required to follow

the ID&E Plan for all work and other requirements as necessary. "All work" includes

additional sampling, or other investigative or remedial planning activities as well as

remediation activities. All parties shall adhere to the requirements and procedures in

the ID&E Plan when conducting activities at the Site.

k*

i 1.4 WORK PLAN OVERVIEW AND PURPOSE L

This work plan for the EE/CA of mine waste piles is intended to guide the

^ characterization of the mine waste piles including field activities and laboratory analyses. Data needed to develop and select removal/remedial alternatives for those mine waste

; piles that contain average lead concentrations greater than 2,000 ppm will also be

m& collected during this investigation.

i

*• Section 1.0 presents the overall objectives and background information for the program. The scope of the investigations under this work plan is presented in Section 2.0. The

L. Sampling and Analysis Plan applicable to this investigation is provided in Section 3.0.

The preparation of the Final EE/CA Report is discussed in Section 4.0. The schedule

w

 for completion of this work is presented in Section 5.0. References are provided in

Section 6.0. Standard Operating Procedures specific to the mine waste piles EE/CA are

 2- SIT E CHARACTERIZATION

: This section discusses the proposed work necessary to characterize the 30 mine waste

"~ piles belonging to Categories 2 and 3 in the residential areas of Leadville and one pile

belonging to Category 1, for a total of 31 piles. U

2 .1 DATA QUALITY OBJECTIVES L Data quality objectives (DQOs) are defined as statements which identify the objectives

of the work and specify the quality, quantity, and analytical level of the data required to

w make decisions relative to these objectives. DQOs for the mine waste piles are

: established to ensure that the data collected are of sufficient quantity and quality for the

*"" intended uses. Data on mine waste piles will be used for the following:

*• • Site Characterization

• Evaluation and Selection of Remedial/Removal Alternatives, if necessary L Once the remedial alternative is selected, the data will also be used for remedial design

1 and monitoring during remedial/removal action. Additional information may, however,

be required for remedial design and for the implementation of the remedial action

selected. Data needs and uses of the data to be collected for this work plan are ^

summarized in Table 2-1.

I

^- The data to be collected for this work plan will be of Analytical Level III. Chemical

analyses will be performed by Test Methods for Evaluating Solid Waste, L Physical/Chemical Methods (SW-846, Third Edition and Final Update I, EPA 1993a), Field and Laboratory Methods Applicable to Overburden and Minesoil (EPA 1978), and

, Annual Book of ASTM Standards (ASTM 1993).

 22 DATA NEEDS FOR EE/CA REPORT

The investigation of the 31 mine waste piles will proceed as shown in Figure 2-1. Each

~~ mine waste pile will be sampled for total lead in the surficial material (0-2" depth) and

; " near-surface material (2-24" depth). Those piles found to average 2,000 ppm lead or less

^" will be retained on hold until the final ROD is completed. Alternatively, with

i-- - concurrence from EPA and the Colorado Department of Health (CDH) , these piles may L be removed and used elsewhere on-site as construction materials, if they do not produce

_ acid. One possible use for these materials would be as capping material for remediation

^ of tailings sites. For those piles containing an average of greater than 2,000 ppm lead,

the bulk samples will be further characterized as described below. The additional data

I to be collected for these piles are classified in two categories: geotechnical and

geochemical.

*•* 2.2.1 Geotechnical Data Needs

i ' \L* Geotechnical information is needed for physical characterization of the mine waste

;- materials for use in the identification and evaluation of remedial/removal action

^ alternatives, if necessary. The information needed for these purposes consists of:

. • External geometry of the mine waste piles, including dimensions, steepness

of slopes, and retaining structures, if any

w

 • Geotechnical characteristics of the mine waste including material

classification and engineering properties

- 222 Geochemical Data Needs

w- The additional geochemical data needed consists of: L

• Leaching potential of a composite sample of the mine waste materials by

\ EPA Method 1312

~l_/^ 22909N-22327/R4J.2 07-25-94C7:27«m)/RPT/31 2-2 L "—
Woodward-Clyde

i • Acid/base accounting of the mine waste materials to estimate the

potential of the mine waste materials to generate and/or neutralize acid

~~ • Kinetic (humidity cell) testing (if necessary) to further evaluate the ability

of the mine waste materials to produce and/or consume acid over time

2J PROPOSED WORK

U The following sections discuss the proposed approach to the characterization of the 31

; mine waste piles and evaluation and selection of removal/remedial actions, if necessary.

1 23.1 Surface Samplin g for Total Lead Content

w

Each of the 31 mine waste piles will be sampled to measure the total lead content of the

i- surficial materials (0-2" depth) and the near-surface materials (2-24" depth). If a pile

;- appears to be composed of two or more distinct materials, each portion of the pile will

L be sampled independently. One composite sample of at least 25 pounds of mine waste

material will be collected from nine subsamples collected from 0-2" depth, and one

i composite sample will be collected from 2-24" depth. Subsamples will be located as

shown in Figure 2-2 and collected as described in SOP Mine Waste No. 2. If the pile

. diameter exceeds 200 feet, then eight additional subsamples will be collected from near

the perimeter of the pile. Additional subsamples may also be collected if nine

subsamples are deemed to be insufficient to properly characterize the pile. Each

*- composite sample will be sieved in the laboratory through a No. 60 mesh. The initial

<-• weight of the sample and the weight of the material passing the No. 60 mesh will be

L recorded. The fine fraction (material passing the No. 60 mesh) will be analyzed for total

_ lead.

i

w

2J.2 Additional Geochemical Testing

!

|

(^ , As shown in Figure 2-1, the mine waste piles containing an average lead concentration

* greater than 2,000 ppm will be further characterized by geochemical testing in the

*~ laboratory. The additional testing may include:

22909N-22327/R45.2 07-25-94(7:12pm)/RPT/31 2-3
\

Woodward-Clyde

L

* . • Subsamples from the composite samples for each pile will be separated for

analysis of the acid-base accounting analytes listed in Table 2-2. In

addition, leaching potential will be evaluated for a composite of these

"~ samples by EPA Method 1312 for arsenic, cadmium, lead, and zinc.

*— • If the acid-base accounting results suggest that the mine waste materials

are net acid-producers, then kinetic (humidity cell) testing may be

L. performed on selected samples from the particular mine waste pile to

^ better characterize the potential of the materials to generate acid.

u_ • All samples collected will be archived for possible future analyses.

Acid-Base Accounting

u

 This series of tests (static testing) measure the total content of various forms of sulfur

p as well as the total content of neutralizing material to estimate the potential of the

^- tested materials to generate and/or neutralize acid. The test results will be used to

categorize the materials as potentially acid generating or non-acid generating. Samples

L. with potential for acid generation may then be subjected to kinetic testing to better

define their ARD potential.

f a« Kinetic Testin g (Humidit y Cell)

^ This test measures the ability of samples to produce and/or consume acid over time by

~~ simulating field weather conditions in the laboratory. This is a refinement over the static

*•• testing program as some allowance for kinetically slow and/or incomplete pyrite

;- oxidation is made. Selected samples which classify as potentially acid generating during

w the static testing program will be subject to kinetic testing, if necessary.

! Samples which still classify as potentially acid generating following humidity cell testing

may then be subjected to more refined testing, or alternatively, may be removed or

i remediated in place as acid-generating materials. Additional testing could include

column testing in the laboratory or test fills in the field.

L Woodward-Clyde L

- , 2.33 Geotechnical Testin g

The geotechnical laboratory testing program will primarily consist of classification

~ testing, and moisture content testing. Classification testing will be used to characterize

"~ and group the materials. Moisture content testing will be used to evaluate handling and

*•» placement requirements for materials to be relocated.

L The geotechnical laboratory testing program may include the following components:

^ • Particle size distribution: ASTM D421 and D422

• Atterberg limits (liquid limit and plasticity index): ASTM D4318

i • Moisture content: ASTM D2216

w

~ The geotechnical testing program will be finalized upon completion of the sampling

^ program based on field observations, the types of materials encountered, samples

p recovered, and engineering judgment. L

23.4 Deferred Testin g

The material remaining from each composite sample will be archived for possible future

, testing. Additional geotechnical testing may be appropriate for materials from any of

the sampled mine waste piles if they are to be placed in a controlled manner in either

i a waste consolidation area or as part of a waste repository /waste encapsulation system.

v

 This testing could include the followin g components:

i- • Compaction: ASTM D 698

• Permeability: ASTM D 5084

L • Consolidation: ASTM D 2435

• Triaxial Shear: U.S. Corps of Engineers (USCE) EM 1110-2-1906

1 • Direct Shear: U.S. Corps of Engineers (USCE ) EM 1110-2-1906

! Specific test requirements would be a function of the material type and proposed use. Additional sampling and testing of relocated materials would also be possible during the

The Sampling and Analysis Plan (SAP) is composed of the following parts:

• Field Sampling Plan

L • Quality Assurance Project Plan

• Standard Operating Procedures L

3 .1 FIELD SAMPLING PLAN

This field sampling plan (FSP) describes the sampling tasks required for the EE/CA of

31 mine waste piles located within the residential areas of the California Gulch Site. 1 The FSP details the sample types, locations and frequency, sample handling and labeling,

planned analyses, documentation and reporting, and quality assurance/quality control

i- (QA/QC) requirements.

II^ 3.1.1 Samplin g Objectives, Locations, and Frequency

i The objectives of the sampling program for the mine waste piles are to (1) evaluate if

the average lead content of the surficial mine waste materials (0-2" depth) and near1 surface material (2-24" depth) exceeds 2,000 ppm, (2) characterize the ARD potential,

neutralization capacity and leaching potential of those mine waste piles which contain

and average of greater than 2,000 ppm lead, and (3) evaluate the physical characteristics

L- of the mine waste materials for piles which contain an average of greater than 2,000 ppm

i lead.

fe*

Samples will be collected from each of the 31 mine waste piles to meet the above

^ objectives. Analyses to be performed are listed in Table 3-1.

i Specific sampling locations will be designated in the field upon site reconnaissance prior

to the start of the investigation.

L 3.2 QUALITY ASSURANCE PROJECT PLAN

! The purpose of the Quality Assurance Project Plan is to document the quality assurance

requirements applicable to activities performed as part of the EE/CA. This plan

| describes the requirements of the quality assurance (QA) program for organizing,

*" planning, performing, reviewing, and documenting activities which affect the quality of

i work related to the EE/CA. It applies to work performed at the California Gulch Site

L and vicinity, in the office, and laboratory testing.

L 3.2.1 Project Organization

i The organization, responsibilities, and qualifications of key personnel concerned with

quality assurance for the EE/CA Work Plan are specified in Subsection 2.2 of the

l Quality Assurance Project Plan, Yak Tunnel Operable Unit, California Gulch Site,

^ Leadville, Colorado (Res-Asarco 1993) (Yak Tunnel QAPP).

i- 3.2.2 Quality Assurance Objectives

L The overall QA objective for this project is to develop and implement procedures for

obtaining and evaluating data that assure that (2) all measurement data have the

i appropriate degree of precision, and accuracy, for the data uses specified in Sections 2.1

and 2.2 (1) sample collected are representative of actual field conditions.

The following sections of the QAPP describe the procedures that need to be

implemented in order to maintain a consistent quality of the data. This consistency will

^- be accomplished through the formal standardization and documentation of field

, procedures and tasks. In addition, project deliverables will be distributed and reviewed

Site Selection and Samplin g Procedures

Section 3.1, Field Sampling Plan, presents a discussion of the Site Selection and

Sampling Procedures. In summary, surface and near-surface samples collected from

31 mine waste piles will be analyzed for total lead. Based on the total lead results,

L. additional mine waste samples collected from those piles which contain an average of

greater than 2,000 ppm lead may be analyzed for the acid-base accounting analytes listed

^ in Table 2-2. One sample per pile may also be analyzed for leaching potential of

arsenic, cadmium, lead, and zinc by EPA Method 1312. Humidity cell testing may be

< performed on selected samples, if necessary, to better characterize their ARD potential

after analysis and interpretation of the acid-base accounting testing.

i

i*•" 3.2.4 Analytical Procedures and Calibration

IL The analyses to be performed on the samples collected during implementation of the

EE/CA Work Plan are listed in Table 3-2. The parameters which will be analyzed are

L, specified in Table 2-2 and the analytical methods are specified in Table 3-3.

I The calibration procedures and frequency of calibration for laboratory equipment

used for sample analysis will be consistent with the protocols specified in the

| methods. L.

32.5 Data Reduction, Validation and Reporting

t_ The analytical data generated by the laboratory will be evaluated for precision, accuracy,

L_ and completeness using specific data validation procedures. All data will go through two

levels of complete data review and validation. The followin g sections describe

i

1 procedures which should be followed by the laboratories and data validation staf f

selected for this project.

The first level of review, which may contain multiple sublevels, will be conducted by the

I analytical laboratory data reviewer who has the initial responsibility for the correctness

u

 and completeness of the data. It is the responsibility of the analytical laboratory to

perform this first level of review to evaluate the quality of the analyses performed, and L

_?-> 22909N-22327/R4J.3 07-21-94(4:23pm)/RPT/31 3-4
L Woodward-Clyde L

[ to confirm that the appropriate analytical method protocols and procedures, including QA/QC requirements, have be followed.

All data will undergo a second level of review. A description of the analytical quality

control criteria to be used in validation of samples analyzed during this second level of

^- review are outlined below. As the analytical methods do not have specific data

validation guidance procedures, the draft EPA Contract Laboratory Program (CLP) L. Functional Guidelines for Evaluating Inorganics Analyses (EPA 1988b) shall be used as

general guidance where pertinent to each analytical method.

be T he QA/QC acceptance limits for matrix spike/duplicate (MS/D) and Laboratory

1 Control Sample (LCS) analyses are shown in Table 3-5. The criteria shall be used

during the data validation process to evaluate the acceptability of the analytical data.

i Acceptance criteria for the homogenized field duplicates will follow the criteria from

*•• Function Guidelines for laboratory duplicates.

L

L The analytical methods will contain quality control measures which allow for validation

in accordance with Data Validation Functional Guidelines for Inorganic Analyses

(Inorganic Guidelines) and are in keeping with the QA/QC acceptance criteria. The

validation will follow the guidance from Functional Guidelines for all criteria contained

i in the Guidelines pertinent to the analytical method, and data will undergo evaluation

of the following:

i

• Holdin g Times

L

* Calibration

• Blanks

, • Laboratory Control Sample

L>: 3.2.6 Quality Assurance and Quality Control Checks (QA/QC)

) The analytical laboratory shall meet the QA/QC requirements stipulated for each

*~ analytical method. Analysis and reporting of a method blank and laboratory control

sample (LCS) shall be included with each sample data package.

QA/QC samples will be submitted to the analytical laboratory for blind field duplicate

L analyses, rinsate blank analyses and for MS/D analyses. One QA/QC sample suite will

be collected from a "sulfide" mine waste pile, and one suite from a "carbonate" mine

[_ waste pile and submitted for analysis. The QA/QC sample suite for each of the "sulfide"

and "carbonate" mine waste piles will be collected from the same sample location, and

1 will be specified prior to commencement of the sampling program. A brief description

f or these QA/QC samples follows:

i*" Field Duplicates

L Field duplicates are prepared as part of the field sampling program by homogenizing,

or mixing, a large portion of a sample and placing equally representative samples into

^ two sets of containers. Comparison of the analytical results for homogenized field

duplicate samples provide a measure of the sampling and analytical precision. Field

I duplicates will be submitted to the laboratory as blind samples. Two blind field

duplicates will be collected, one from a "sulfide" mine waste pile and one from a

1

 "carbonate" mine waste pile.

c.

Rinsate Blanks I — ———

ka

, Rinsate blanks are collected by pouring deionized water over the sampling equipment

L after it has been decontaminated and prior to use in the field. Rinsate blanks are often

referred to as equipment blanks or as decontamination procedure blanks. They are

I collected to check for sample contamination caused by reuse of decontaminated

sampling equipment as well as the sampling process and transportation. Two rinsate

\ samples will be collected, one sample each following decontamination of equipment from

a "sulfide" mine waste pile and a "carbonate" mine waste pile.

iL Woodward-Clyde L

^ Matrix Spike (MS) and Duplicate (D) Samples

Matrix spike sample analyses are used to evaluate the effect of the sample matrix on the

accuracy of the laboratory method. Matrix spikes are field samples spiked with known

quantities of specific compounds and processed through to the entire analytical

•"• procedure and the recovery of the compounds calculated. Results are expressed as

. percent recovery of the known amount spiked. Laboratory duplicates are two aliquots

L of a single homogeneous sample which are analyzed for the same parameter in order to

determine the precision of the method. Results are expressed as relative percent

^ difference.

• A sufficient quantity of material of the specified field sample selected for MS/D analysis

^^ _ will be collected in the sample container. Two samples will be selected for MS/D

analyses, one from a "sulfide" mine waste pile and one from a "carbonate" mine waste

"- pile.

i

^ No project specific performance or systems audits are anticipated during implementation

of the EE/CA Work Plan. L

3.2.8 Calculation of Data Quality Indicators

Calculation of accuracy (as percent recovery/ and precision (as relative percent

difference between duplicate results) will be in accordance with formula described in u

 Section 8.4 of the Yak Tunnel QAPP Functional Guidelines.

»L. The analytical completeness will be calculated by the ratio of total valid analytical data

results (including estimated values) to the total number of analytical results requested

^ on samples submitted for analysis. The equation for analytical completeness is:

The analytical completeness goal is 90%. If the goal is not met, the Project Manager,

in concurrence with EPA and CDH, will decide if the data are sufficien t for its intended

use. If it is judged that the data are inadequate, additional field samples may be

collected and analyzed to meet project goals.

3.2.9 Corrective Action Procedures

i Corrective action procedures may be implemented by the Asarco Project Manager if they

consider any aspect of the program is unacceptable. Correct Action Procedures

i ^ implemented would follow the procedures described in Section 12.0 of the Yak Tunnel

*" SAP.

L 3.2.10 Quality Control Reports

^ For this project, no separate reports will be prepared to describe the results of the QA

program described in this QAPP. Data summaries and evaluations of QA/QC data will

I be provided as necessary in the controlled documents required by the SOW.

| 3.1.11 Data Management L

. Analytical data collected during the Mine Waste EE/CA investigations will be input into

*- the project database. The database will be maintained on a microcomputer and

structured so that all tasks associated with electronic data transfer from the analytical

{^ laboratory, data entry, processing, analysis, and reporting can be accomplished in an

efficien t and verifiable manner. Data from the database will be exported as needed to

! other software packages for statistical analysis, graphical output, and data tabulations

associated with routine data evaluation and reporting. The file structure will be

! compatible with the EPA/Roy F. Weston EDMS system.

L PURPOSE AND SCOPE

The purpose of this document is to define the standard operating procedure (SOP) for

collecting mine waste samples to 24 inches below the surface, during the Mine Waste

Piles EE/CA at the California Gulch Site. The purpose of the sampling program is to

obtain samples which meet the objectives of the investigation as defined in

Subsection 3.1.1 of the Mine Waste Piles EE/CA Work Plan. This procedure is

intended to be complete enough so that steps which could affect tracking,

documentation, or integrity of samples have been explained in sufficient detail that

differen t sampling personnel followin g these procedures will deliver samples to the

laboratory which are equally reliable and consistent.

This procedure gives descriptions of equipment, field procedures, sample handling,

documentation, and field quality assurance/quality control (QA/QC) procedures

necessary to collect near-surface mine waste samples at the site.

This procedure is to be strictly followed. Any modification to the procedure shall be

approved in advance by the Project Manager.

Other SOPs will be used with this procedure, including:

• SOP No. 1 - Decontamination (Res-ASARCO 1990a)

• SOP No. 10 - Sample Handling, Documentation, and Analysis (Res- ASARCO 1990a)

SAMPLES

6 .1 SAMPLE IDENTIFICATION, LABELING, AND HANDLING

Mine waste samples will be collected in glass jars as described in Table 3-2 of the Field

V j, Sampling Plan. All samples will have a label attached which will be filled out using

waterproof ink as described in SOP No. 10 (Res-ASARCO 1993). Sample identification

| numbers will follow the conventions discussed in SOP No. 10. After collection, samples

will be handled, shipped, and tracked as specified in SOP No. 10.

A chain-of-custody (COC) form shall be filled out in the field, and this form shall

! accompany every shipment of samples to the laboratory. The chain-of-custody procedure

^- is specified in SOP No. 10.

k 62 QA/QC SAMPLES

t_ QA/QC samples will be submitted to the analytical laboratory for blind field duplicate

analyses, rinsate blank analyses and for MS/D analyses. One QA/QC sample suite will

I be collected from a "sulfide" mine waste pile and one suite from a "carbonate" mine

waste pile and submitted for analysis. The QA/QC sample suite for each of the "sulfide"

and "carbonate" mine waste piles will be collected from the same sample location, and

will be specified prior to commencement of the sampling program. A brief description

f or these QA/QC samples follows:

62.1 Field Duplicates

Field duplicates are prepared as part of the field sampling program by homogenizing, I or mixing, a large portion of a sample and placing equally representative samples into

two sets of containers. Field duplicates will be submitted to the laboratory as blind

I samples. The true identity must be thoroughly documented in field notes. This

documentation is not submitted to the laboratory. Two blind field duplicates will be

^ collected, one from a "sulfide" mine waste pile and one from a "carbonate" mine waste

pile.

*"" 622 Rinsate Blanks

** Rinsate blanks are collected by pouring deionized water over the sampling equipment

, after it has been decontaminated and prior to use in the field. Rinsate blanks are often

L referred to as equipment blanks or as decontamination procedure blanks. They are

collected to check for sample contamination caused by reuse of decontaminated

i sampling equipment as well as the sampling process and transportation. Two rinsate

samples will be collected, one sample each following decontamination of equipment from

I a "sulfide" mine waste pile and a "carbonate" mine waste pile.

! 623 Matrix Spikes (MS) and Duplicate (D) Samples

L

Matrix spike sample analyses are used to evaluate the effect of the sample matrix on the

accuracy of the laboratory method. Matrix spikes are field samples spiked with known

quantities of specific compounds and processed through to the entire analytical

procedure and the recovery of the compounds calculated. Results are expressed as

percent recovery of the known amount spiked. Laboratory duplicates are two aliquots

L of a single homogeneous sample which are analyzed for the same parameter in order to

determine the precision of the method. Results are expressed as relative percent

; difference. L*

A sufficien t quantity of material of the specified field sample selected for MS/D analysis

U will be collected in the sample container. Two samples will be selected for MS/D

analyses, one from a "sulfide" mine waste pile and one from a "carbonate" mine waste

iL pile.

1 .0 INTRODUCTION AND TYPES OF CONTAMINATION

The purpose of this document is to define the standard procedure for decontamination for the Yak Tunnel Operable Unit project. This Standard Operating Procedure (SOP) serves as a supplement to the Quality Assurance Project Plan (QAPP) and the Field Sampling Plan (FSP). This procedure is intended to be used together with the SAP and the other SOPs.

1.1 PERSONNEL EXPOSURE

I Workers involved in site activities may come into contact with soils,- surface water, ground

water, and sludges from the Yak Tunnel Operable Unit. Assessments of the area have identified

the potential contaminants as metals and silica. These constituents are not considered toxic to I humans by dermal route, although they may cause skin irritation at concentrations much higher

than those found in the Yak Tunnel Operable Unit to date. Extended dermal exposure to open

wounds, however, could lead to uptake of toxic constituents. The Yak Tunnel effluen t water

1 is slightly acidic. Physical contact with drainage water for long periods of time may cause slight

irritation due to the pH. It is also known to cause some skin discoloration. Ingestion of soils

. , and Yak Tunnel effluen t is to be avoided. Inhalation of soils during operations producing

^ respirable dust is another possible exposure route. As outlined in the Health and Safety Plan,

the exposure will be controlled through the use of respirators as necessary based on air

monitoring results. A splash into the eye is expected to cause irritation due to the acidity of the

^ effluent s and is to be avoided. Exposure to potential dermal and ingestion routes will be limited

by decontamination procedures, site prohibitions and the use of personal protection equipment.

L 1.2 SITE AND/OR SAMPLE CROSS-CONTAMINATION

The overall objective of multimedia sampling programs is to obtain samples which accurately L, depict the chemical, physical, and/or biological conditions at the sampling site. Extraneous

contaminant materials can be brought onto the sampling location and/or introduced into the

medium of interest during the sampling program (e.g., by bailing or pumping of ground water L with equipment previously contaminated at another sampling site). Trace quantities of these

contaminant materials can thus be captured in a sample and lead to false positive analytical I results and, ultimately, to an incorrect assessment of the contaminant conditions associated with L. the site. Decontamination of sampling equipment (e.g., bailers, pumps, tubing, soil and

1 sediment sampling equipment) and field support equipment (e.g. , drill rigs, vehicles) is therefore

 required at the Yak Tunnel Operable Unit to ensure that sampling cross-contamination is

t- prevented, and that on-site contaminants are not carried off-site.

! 2.2.2 Sampling Equipment L. The followin g steps will be used to decontaminate sampling equipment that has been exposed

; to known or suspected hazardous materials (including reusable filter apparatus):

• Personnel will dress in suitable safety equipment to reduce personal exposure.

• Gross contamination on equipment will be scraped off at the sampling or

construction site.

Ui

 • Equipment that will not be damaged by water will be placed in a wash tub

containing Alconox or low-sudsing detergent along with potable water and

•^ scrubbed with a bristle brush or similar utensil. Equipment will be rinsed with

potable water in a second wash tub followed by a nitric acid solution (10%) rinse,

a distilled, metal-analyte-free water rinse, and drying with paper towel.

• Equipment that may be damaged by water will be carefully wiped clean using a

sponge and detergent water or spray bottle and towel and rinsed with distilled,

i... metal-analyte-free water. Care will be taken to prevent any equipment damage.

; • Rinse and detergent waters will be replaced with new solutions between borings L or sample locations.

Following decontamination, equipment will be placed in a clean area or on clean plastic sheeting L to prevent contact with contaminated soil. If the equipment is not used immediately, the

equipment will be covered or wrapped in plastic sheeting or heavy duty trash bags to minimize

potential airborne contamination.

1.0 PURPOSE AND SCOPE

The purpose of this document is to define the standard protocols for sample handling,

documentation, and analysis for the Yak Tunnel Operable Unit project. Thi s Standard Operating Procedure (SOP) serves as a supplement to the Quality Assurance Project Plan (QAPP) and the Field Sampling Plan (FSP). This procedure is intended to be used together with the FSP and

other SOPs and is referenced in all SOPs that apply to sampling.

2 .0 PROCEDURES FOR SAMPLE HANDLING, DOCUMENTATION, AND ANALYSIS

2 .1 SAMPLE IDENTIFICATION AND LABELING

Samples collected during treatment plant operations or routine monitoring activities will be

assigned unique sample identification numbers. Each sample identification number will identify

the organization collecting the sample or the program under which it is collected, sampling

location, type of sample, and sampling sequence for each sample. These numbers are required

for tracking the handling, analysis, and verification or validation status of all samples collected

during water treatment plant operations and routine monitoring. In addition, the sample

identification numbers will be input into the project database to identify analytical results

received from the laboratory.

Sample identification numbers that are assigned will be divided into four fields as shown in the

following example:

R-YFW-01-900423

The first field is one character in length and identifies the company conducting the sampling. The second field is a three or four character alphanumeric code identifying the location of the

sample (e.g., YFW indicates Yak Flow Water or Yak Portal discharge water). The next field

identified is the type of sample being collected; this is used to identify whether the sample is a

primary or grab sample, a composite sample, field duplicate, field blank, equipment rinsate, or

matrix spike sample. The final field contains the date in a year-month-day format to allow data

in the analytical database to be easily sorted. For example, the sample identified above was

collected on April 23, 1990. Table 1 provides a list of the possible code entries for each of the

data fields for water treatment plant, surge pond, and routine monitoring samples.

Each sample that is collected in the field will be labeled for future identification. Sample labels

will be filled out as completely as possible by a member of the sampling team prior to the start

of the day's field sampling activities. The date, time, sampler's signature, and the last field of

the sample identification number should not be completed until the sample is actually collected. All sample labels will be filled out using waterproof ink. At a minimum, each label will contain

the following information:

•>.!«.« 10-3 Baker Consultants, Inc.
SOP NO. 10

• Sampler's company affiliation ; • Site location;

• Sample identification; • Date and time of sample collection; • Analyses required;

• Method of preservation used;
