1 INTRODUCTION

1.1 BACKGROUND TO THE ASSESSMENT

Castle Peak Power Company Limited (CAPCO) proposes to install up to two

additional gas-fired generation units (combined cycle gas turbine, CCGT) at

Black Point Power Station (BPPS) (hereafter referred to as “the Project”) to

increase the use of natural gas for local power generation and reduce the

carbon intensity of local electricity generation. The Project requires an

Environmental Permit from the Hong Kong SAR Government. In relation to

this, CAPCO has prepared a Project Profile for application for an

Environmental Impact Assessment (EIA) Study Brief, which was submitted to

Environmental Protection Department (EPD) on 22 April 2015. The EIA

Study Brief (No. ESB-286/2015) (hereafter referred to as “the Study Brief”)

was issued by EPD on 2 June 2015.

Environmental Resources Management (ERM) was commissioned by CAPCO

for the EIA Study for the proposed Project. In accordance with Clause 3.4.8

and Appendix D2 Requirements for Assessment of Land Contamination of the

Study Brief, land contamination assessment shall be carried out for the Project.

A Contamination Assessment Plan was prepared and approved by EPD on 4

November 2015 (hereafter referred as “the Approved CAP”). Subsequent to

the CAP approval, site investigation (SI) was conducted between 5 November

and 23 November 2015. This Contamination Assessment Report (CAR) is

prepared to present the findings of the SI.

3 SUMMARY OF SITE INVESTIGATION

The SI was conducted by CAPCO’s Geotechnical Contractor, Gammon

Construction Limited (Gammon) from 5 November 2015 to 23 November

2015. Soil and groundwater sampling were supervised by a land

contamination specialist of ERM.

3.1 SOIL SAMPLING

For safety reasons, underground utility clearance was conducted at each of the

sampling locations before drilling. Inspection pits were excavated manually

down to 1.5m bgl, as far as practicable (actual sampling depths refer to Table

3.1 below). Drilling was then advanced continuously from 1.5m bgl by dry

rotary drilling method. Three rotary drilling rigs were mobilised for the

sampling exercise. Water was used as a flushing medium when rock or

boulders were encountered during drilling. Soil was retrieved at

approximately 1m intervals for inspection for geological characteristics and

for visual inspection for potential contamination (such as visual evidence of

discoloration, stains, presence of non-aqueous liquid phase or abnormal odor).

Nine boreholes (BH1 to BH9) were advanced down to a maximum of 7.50m

bgl and two boreholes (BH10 and BH11) were advanced down to 3.0m bgl.

Soil sampling was conducted by ERM site supervision staff on site. The

details of the soil drilling and sampling are summarised in Table 3.1. Strata

logging for boreholes was undertaken by a qualified geologist. The logs

include the general stratigraphic description, depth of soil sampling, sample

notation and level of groundwater. The presence of rocks/boulders /cobbles

and foreign materials such as metals, wood and plastics (if any) was also

recorded. Gammon also conducted the level survey of each borehole,

including as-built coordinate of sampling locations, level of the monitoring

well cap (mPD) and ground level of boreholes (mPD). Representative

photographs taken during the SI are presented in Annex B. Ground

investigation logs are provided in Annex C.

Notes:

(a) Soil duplicate sample was collected at 0.5 m bgl

(b) The soil strata recovered from the location is mainly boulders and rocks, no soil sample can

be collected.

(c) Soil duplicate sample was collected at 1.5 m bgl

(d) Exact sampling depths may be different from the proposed sampling depths in the

Approved CAP. This is due to the presence of boulders/ rock at the proposed sampling

depths.

Soil samples to be delivered to laboratory for analysis were subject to on-site

VOCs test with the use of a Photoionising Detector (PID). The range of VOCs

concentrations detected ranging from 0.0ppm to 1.0ppm. The PID results

showed no abnormally high VOCs reading. No visual or olfactory sign of

contamination (e.g. discoloration of soil, foul odour) was observed at the

boreholes during the SI. Table 3.2 summarised the results of the PID test.

(b) Sampling depths at BH1, BH2, BH3, BH9, BH10 and BH11 are different from the

proposed sampling depths in the Approved CAP. This is due to the presence of

boulders/ rock at the proposed sampling depths.

3.2 GROUNDWATER MONITORING WELL INSTALLATION AND WELL DEVELOPMENT

Nine of the boreholes conducted (BH1 to BH9) were converted into

groundwater monitoring wells using uPVC perforated piping with a machine

slotted section (1mm or less slot aperture). The well screens were installed at

a minimum of 1m above and 2m below the groundwater level. Well caps

were secured to prevent contamination from the surface by filling bentonite

and cement to the top of the void. A typical design of a groundwater

monitoring well is shown in Annex D.

No groundwater was encountered at BH10 and BH11 and therefore no

groundwater monitoring well was installed at both locations.

Prior to the groundwater sampling, the monitoring wells were developed by

bailing at least five times the well volume to remove standing water and allow

for replenishment. The static groundwater levels were measured with an

electronic groundwater level indicator in each well. The details of the

groundwater wells installed and groundwater levels recorded are provided in

Table 3.3.

During groundwater sampling, no visual or olfactory sign of groundwater

contamination (e.g. presence of Non-Aqueous Phase Liquid (NAPL)) was

observed

(b) A water sample duplicate is taken at this groundwater well.

(c) No groundwater was encountered at this borehole and no groundwater sample was

collected.

3.3 DECONTAMINATION OF EQUIPMENT

Sampling equipment used during the course of the SI was thoroughly

decontaminated, to minimize the potential of cross-contamination. All

equipment were decontaminated using a non-phosphate soap solution and

water, with a distilled water rinse to clean all smaller pieces of equipment, in

particular those used to sample materials such as sampling cores, hand

excavation and grab samples. This cleaning procedure was repeated after

use at each borehole to avoid potential cross contamination between

boreholes.

Larger equipment and materials were steam cleaned using mains water,

where possible, or at a minimum pressure jet washed with mains water prior

to mobilisation to the Site.

During sampling and decontamination activities, disposable latex/nitrile

gloves were worn to prevent transfer of contaminants from other sources.

Any disposable equipment was disposed as general waste after each use.

3.4 FIELD QA/QC IMPLEMENTATION, SAMPLE PRESERVATION AND DELIVERY

A QA/QC programme was incorporated for the assessment. The

programme included collection/preparation and analysis of field QA/QC

samples and laboratory internal QA/QC samples.

The field QA/QC samples included two sets of soil duplicates, one set of

groundwater duplicates, four sets of field blanks, three sets of equipment

blanks, and nine trip blank samples. These duplicates and field blank

samples were analysed for the same suite of parameters as of the other

samples. The equipment blank sample was collected for the soil sampling

equipment and analysed for the target priority pollutant metals.

The laboratory QA/QC samples including method blanks, surrogates, matrix

spikes and etc were prepared and analysis by the contracted laboratory, ALS

Technichem (HK) Pty Ltd (ALS), in accordance with relevant USEPA’s

standard methods and procedures.

ERM supervised the soil and groundwater sampling to meet the requirements

of the project QA/QC and the decontamination procedures. All soil and

groundwater samples (including QA/QC samples) were kept in a refrigerator

at 4ºC for delivery. The samples were delivered on ice with Chain of Custody

to a courier and arrived at the laboratory within the sample holding time.

The Chain of Custody for the samples was maintained from the time of

sample collection to sample arrival at the testing laboratory. The written

record of sample handling is intended to ensure prompt sample analysis and

integrity.

4 ANALYTICAL RESULTS AND INTERPRETATION

4.1 RBRG - LAND USE SCENARIOS

With reference to the Risk Based Remediation Goal (RBRG) Guidance Manual,

the RBRG (Industrial) Criteria were adopted for the interpretation of results.

Comparisons were made with the RBRGs stipulated in Table 2.1 and Table 2.2

of the RBRG Guidance Manual. These tables are extracted and attached as

Annex E.

RBRGs were developed for four different post-restoration land use scenarios

reflecting the typical physical settings in Hong Kong under which people

could be exposed to contaminated soil and groundwater. It is anticipated

that the area occupied by the Project will be developed for the new CCGT

development and therefore is classified as industrial land use.

In addition to the RBRGs, Non-aqueous Phase Liquid (NAPL) screening

criteria (soil saturation limits, Csat in soil and solubility limits in groundwater)

were also referenced.

The laboratory analytical results for the soil and groundwater are summarised

in Annex F and are discussed in the following sections. Full laboratory

analytical reports are provided in Annex G.

4.2 SOIL SAMPLE RESULTS AND INTERPRETATION

A total of 29 soil samples (including two soil duplicates) were collected from

this SI programme. Heavy metals, petroleum carbon ranges (PCR), VOCs,

4.3 GROUNDWATER SAMPLE RESULTS AND INTERPRETATION

A total of ten groundwater samples (including 1 duplicate sample) were taken

during the SI programme. The concentrations of testing parameters,

including mercury, PCR, VOCs, SVOCs and PCBs were below the relevant

laboratory detection limits as well as RBRGs for Industrial land uses/

solubility limits in all groundwater samples tested.

The laboratory analysis results are presented in Annex F and summarised in

Table 4.2.

4.4 QUALITY ASSURANCE / CONTROL

4.4.1 Sample Duplication

The relative percentage difference (RPD) was used to assess the sample

collection and laboratory analysis reproducibility and precision. In

accordance with the USEPA’s guidance, RPDs were only calculated for the

duplicate samples results that were higher than two times of the method

detection limits. The USEPA acceptable limits for the RPDs are less than 50%

for soil samples and 30% for groundwater samples.

The values of RPD calculated for the soil duplicate samples taken at BH2 0.5m

(16.1%) and BH7 1.5m (3.8%) were within the acceptable limits.

4.4.2 Equipment Blank, Field Blank and Trip Blank

Throughout the sampling period, four sets of field blanks, three sets of

equipment blanks and eleven sets of trip blanks were taken and all the results

obtained are below laboratory reporting limit.

4.4.3 Laboratory QA/QC data

The laboratory QA/QC sample results (eg surrogate recoveries, matrix spike

recoveries, method blanks, sample holding time, and other internal laboratory

QA/QC) met their respective requirements.

4.4.4 Sample Results Usability

Based on the review of the QA/QC sample results for this Project, the

laboratory results for the soil and groundwater sample collected for the Project

are considered useable to evaluate the environmental conditions for the

purpose of a land contamination assessment.

5 CONCLUSION

A total of 11 sampling locations were proposed in the Approved CAP for the

SI programme of this Project. SI was conducted between 5 November and 23

November 2015. A total of 29 soil samples (including two duplicate samples)

and 10 groundwater samples (including one duplicate sample) were collected

and analysed by a HOKLAS accredited laboratory. No visual or olfactory

signs of land contamination were observed during soil and groundwater

sampling. Disturbed soil samples were collected at 0.5m and 1.5m while

undisturbed soil samples were collected at 3.0m and 6.0m in accordance with

the Approved CAP, as far as practicable. At some of the sampling locations,

soil samples were not collected at the targeted sampling depths due to the

presence of boulders and rocks.

Among the sampling locations conducted in the SI, two of the locations (BH10

and BH11) were not encountered with groundwater before the borehole end

depth (3.0m bgl). Therefore, both locations were not installed with

groundwater monitoring well and no groundwater sample was collected.

Groundwater samples were collected from BH1 to BH9 at static groundwater

level for analysis.

Heavy metals including Arsenic, Barium, Cadmium, Cobalt, Copper, Lead,

Manganese, Molybdenum, Nickel, Tin, Zinc and Trivalent Chromium were

detected at all soil samples collected. The concentrations detected were well

below RBRGs for Industrial land use and soil saturation limits.

Concentration of PCR, VOCs, SVOCs and PCBs were below laboratory

detection limit for all soil samples analysed. For groundwater samples,

Mercury, PCR, VOCs, SVOCs and PCBs were not detected with concentration

above laboratory reporting limits. Based on the soil and groundwater

analytical results, no sign of land contamination is considered present at the

four Works Areas of this Project and hence no remediation work is deemed

necessary.

Notes:(1) For Dioxins, the cleanup levels in USEPA Off ice of Solid Waste and Emergency Response (OSWER) Directive of 1998 have been adopted. The

OSWER Directive value of 1 ppb for residential use has been applied to the scenarios of “Urban Residential”, “Rural Residential”, and “Public Parks”, while the low end of the range of values for industrial, 5 ppb, has been applied to the scenario of “Industrial”.

(2) Soil saturation limits for petroleum carbon ranges taken from the Canada-Wide Standards for Petroleum Hydrocarbons in Soil, CCME 2000.(3) * indicates a ‘ceiling limit ’ concentration.(4) *** indicates that the C

sat value exceeds the ‘ceiling limit ’ therefore the RBRG applies.

Notes:(1) Blank indicates that RBRG could not be calculated because the toxicity or physical/chemical values were unavailable, or the condition of

Henry’s Law Constant>1.00E-05 was not met for the inhalation pathway.(2) Water solubilities for Petroleum Carbon Range aliphatic C9-C16 and greater than C16 generally are considered to be effectively zero and

therefore the aromatic solubility for C9-C16 is used.(3) * indicates a ‘ceiling limit ’ concentration.(4) *** indicates that the solubility limit exceeds the ‘ceiling limit ’ therefore the RBRG applies.
