1.6. DEVIATIONS TO VERIFICATION PROTOCOL Four deviations from the specific verification protocol are reported from the implementation of the test activities. The deviations and their impact on the verification process are described in section 4.2.3. 2. DESCRIPTION OF THE TECHNOLOGY 2.1 SUMMARY DESCRIPTION OF THE TECHNOLOGY The rainwater leaked in the manholes of the tanks used for the storage of fuels can create noticeable problems of environmental management and compliance with the laws. The meteoric water infiltrated may contain traces of hydrocarbons.

Manholes are expected to be dry and hermetic both for safety reasons and to prevent the leakage of water into the tanks, polluting the fuel.

Actually, despite the correct construction and positioning of the manholes, the normal activity daily involves their opening for the duration of tanks loading and their inspection. If the activity, whose average duration is about 1-2 hours/day, occurs in the presence of rainfall, rainwater can fall into the manholes.

VRT system provides the suction and the following depuration of rainwater in the manholes of fuel storage tanks and in other closed areas characterized by the presence of water polluted by hydrocarbons.

The purpose of the verification is to verify that depurated waters respect the EU legislation for direct discharge in superficial water bodies (Italian D.LGS. 152/06) for total hydrocarbons and total suspended solids.

Most of the components of VRT system are classified as ATEX II and can be installed in explosive environments.

Installation of VRT system, consisting of ATEX II components, properly communicated to competent bodies, does not alter the administrative and control requirements provided by DPR 151 of 01/08/2011, regarding the regulation scheme for the discipline of procedures relative to fire prevention.

CONCEPTUAL DESIGN AND TECHNICAL COMPONENTS The principle used by VRT System is Vacuum suction and physical water treatment with oil separators.The scheme below represents the components of VRT plant that are in summary:

• suction pipes installed in the manholes – PEHD DN 20-25 SDR 11; • collector provided with nr.10 sphere valves installed inside control cabinet; • peristaltic pump ATEX2IIG installed inside control cabinet – suitable for 219 l/h, 650 l/h and 3600 l/h; • ON-OFF pushbutton system ATEXII, installed at the side of control cabinet; • pump discharge pipe – PEHD SDR 11; • electrical panel, installed outside of ATEX zone, 380 V, connected with pushbuttonsystem and pump

in the control cabinet through a 24V (or 230V Atex) cable; • siphon shaft installed underground between control cabinet and oil separator, as fire safety system; • sludge/oil separator, installed underground, provided with coalescent insert, that allows the treatment

of wastewater ensuring a maximal hydrocarbons concentration of 5 mg/l (class 1 according to UNI EN 858);

• sampling shaft, installed underground, to control discharge concentrations according to law-limits.


FUNCTIONING OF THE SYSTEM:

Once it is confirmed the presence of water within a manhole the corresponding valve is opened. Thanks to the on-off pushbutton system the peristaltic pump is activated. The water aspirated from the manhole reach the siphon shaft and then goes into the sludge/oil separator which begins to discharge. When the manhole is completely empty the peristaltic pump is stopped through the pushbutton and the corresponding valve is closed.

The following scheme represents VRT System conceptual design.

The following figure shows a manhole with water leaked in and a VRT system installed.


2.2. INTENDED APPLICATION (MATRIX, PURPOSE, TECHNOL OGIES, TECHNICAL CONDITIONS) VRT system provides the suction and the following depuration of rainwater in the manholes of fuel storage tanks installed by fuel stations, transport areas, private commercial activities and so on.

This system avoids the contamination of terrains and groundwater by collecting contaminated rainwater, treating in oil separator and subsequent conveyance of treated waste water to the existing sewerage system.

Although VRT system is conceived for suction and depuration of the water within the manholes, it can be also used in other closed areas interested by infiltration of water potentially polluted by hydrocarbons. A detailed description of the intended application is described in table 2.

The full range of models of the VRT system includes:

VRT - 219 l/h VRT - 650 l/h

VRT - 3600 l/h

The different names indicate the different peristaltic pump ATEX2IIG installed inside the control cabinet (219 l/h, 650 l/h or 3600 l/h). Normally, the quantity of rainwater that can be found within a manhole does not exceed 100 liters.

Hence, for a fuel service station, the most suitable model of VRT system is VRT - 219 l/h or VRT - 650 l/h. VRT – 3600 l/h is a model to be used only for particular applications. For this reason the EU ETV verification of the VRT systems focused on the verification of the following models:

VRT - 219 l/h (the principle components of this model are the sludge/oil separator NEUTRAcom 3/300 and the peristaltic pump Verderflex VF 15)

VRT - 650 l/h (the principle components of this model are the sludge/oil separator NEUTRAcom 3/300 and

the peristaltic pump Verderflex VF 25)


Table 2: Intended application of the technology

Matrix Purpose Technologies and technical condition s

Soil, ground water, superficial waters.

Simple, efficient and instantaneous suction of rainwater infiltrated within the manholes;

Prevention of the risk of soil and groundwater contamination;

Reducing wear of the metallic components within the manholes;

Lower economic impact in the long term.

The initial conditions under which VRT System is applicable is the presence of rainwater in manholes of fuel storage tanks or in other closed areas.

The separator ordinary maintenance must be carried out twice a year and consists in: - verification of sludge and oil quantities and eventual removal; - verification of correct working and cleaning of the emergency float; - wash of the coalescent filter; - verification of the ATEX II alarm system (if present). Waterflow range that can be treated in VRT system is from 219 l/h up to 3600 l/h.

NOTE: VRT System is not applicable if the percentage of hydrocarbons within the mixture exceeds 5 %, (e.g. in case of incidental fuel spreading). In this case fuel removal must occur through clean truck services in according with applicable laws.

2.3 VERIFICATION PARAMETERS DEFINITION The list of parameters considered in the specific verification protocol is described in Table 3.

Pump discharge parameter shows the water flow rate that can be treated in VRT system by the VRT models VRT - 219 l/h and VRT - 650 l/h. “Total hydrocarbons” and “total suspended solids” parameters have been defined according to the emission values in surface water bodies as for Legislative Decree 152/06 Italian law as transposition of EU norms 96/61/CE, 2000/60/CE, 91/156/CE and followings).

3. EXISTING DATA 3.1. ACCEPTED EXISTING DATA No existing data was submitted by Pozzoli Depurazione.

4. EVALUATION 4.1. CALCULATION OF PERFORMANCE PARAMETERS Pump discharge flow rate The pump discharge flow rate at the siphon shaft was measured. Six measurements of flow rate have been conducted for the model “VRT - 219 l/h” and six measures of flow rate for the model “VRT - 650 l/h”. Table 4 shows the results. Some of the planned measurements were not performed; it was justified in the test registry and in the test report. The average and the confidence interval at 95 % of the confidence level have been calculated. According to the collected values of flow rate it can be confirmed that both the peristaltic pumps respect the claimed nominal values (219 l/h and 650 l/h). All the collected data fall within the claimed range (± 15 %).

4.2. EVALUATION OF TEST QUALITY 4.2.1 CONTROL DATA An In-house method was developed and used. The method developed was included in full in the specific verification protocol and in the test plan. The analytical methods applied were referenced (“APAT CNR IRSA 5160 B2 Man 29 2003 method” and “APAT CNR IRSA 2090 B Man 29 2003”

The test report included the list and summary of any amendments to the test plan and deviations recorded during tests, all analytical and calculated data as well as a reference to the staff that performed the test, the description of test measurements and performance parameters from raw data, the details on equipment used. Regarding the analytical results test reports were drafted by the ISO 17025 test body “Tecnologie d’Impresa Srl”.

A validation of the method has been conducted by Pozzoli Depurazione in order to assess whether the method is fit for the intended use. For this purpose several samples have been collected at the siphon shaft on the 23rd of April 2015 and analyzed by the laboratory – “Tecnologie d’Impresa Srl”.

A test system control was performed by Andrea Invernizzi (Pozzoli Depurazione) at the test site on the 23rd of April 2015 before the starting of the testing activities. The test system control included an evaluation of the following equipment:

• adequate tool to open the manholes; • a graduated rod and a reagent paste to measure the thickness of oil within the separator; • adequate graduated containers to realize the correct water-fuels mixture within manholes and

separator; • a test register and a digital camera in order to document all test procedures; • a graduated beaker of 5000 ml and a chronometer to measure the flow rate within the siphon shaft; • a kit of sampling for total hydrocarbons, supplied by the ACCREDIA certified EN ISO/IEC 17025

laboratory – “Tecnologie d’Impresa Srl” according to APAT CNR IRSA 5160 B2 Man 29 2003 method, that includes 12 clean glass bottles of 1000 ml and what necessary for the stabilization of samples (hydrochloric acid, pipette, dosers, ecc).

It was concluded, that the equipment was suitable for the test activities. An internal audit was conducted by the Internal Auditor (Bruno Soracco) in order to verify the compliance of the testing activities carried out to the test plan and to the specific verification protocol. The internal auditor confirmed the correct modality of execution of the test. Verification registers and spreadsheet used for the collection of data and for the calculations of the results were subject to control and on a sample basis (spot validation of at least 5 % of the data) from RINA.

4.2.2 AUDITS A test system audit was conducted on site on 23/04/15 by Felice Alfieri (ETV Inspector) and Fabio Olivieri (Technical Expert). It was evaluated whether the testing was done according to the requirements specified in the test plan and in the specific verification protocol. In particular the auditing activities carried out included the check of the test equipment, the assessment of the preparation, sampling and handling of samples, the check of the test methods applied, of the measurement traceability, the control of data, the quality assurance activities and the result reporting. It was concluded from the audits, that there was consistency with the test plan and set up and that handling of measurements were carried out as described; testing premise and environmental conditions were in line with the SVP requirements; the sampling was performed according to APAT CNR IRSA 5160 B2 Man 29 2003 method, the samples for total hydrocarbons (collected within clean glass bottles not completely filled)


were taken to pH=2 with 1:1 diluted hydrochloric acid in order to inhibit the bacterial activities. These samples have been put in a refrigerator and conserved at 4°C until the delivery at the laboratory “Tec nologie d’Impresa Srl” located in Via Don Minzoni, 15 Cabiate (CO). The samples have been provided to the laboratory on 23rd of April 2015 according to the laboratory instructions for preparation and delivery according to the test reports provided by the laboratory. The analytical results for the samples have been communicated from the laboratory to Pozzoli Depurazione on 11/05/2015.

Also the quality management system was object of audit. Pozzoli Depurazione is an ISO 9001 Certified Organization. Organizational documents were checked including the quality manual, the organizational charts, training registrations and planning. In conclusion the quality management system complies with the requirements set out in C.III. of the GVP. 4.2.3 DEVIATION Two deviations from the Specific verification protocol are reported. An overview with a description of the deviation and the impact/consequence is given in Table 6.

Table 6: Deviation from the specific verification p rotocol No. Description of deviation Impact / consequence 1 At the test site PV Eni 4817 Viale

Montegrappa 250, 59100 Prato was possible to carry out only two measures of flow rate per manhole because at the same time the operators had to collect samples at the siphon shaft (DEVIATION NR.1)

This deviation has no impact on the demonstration of the respect of the performance claim. The test results are in line with the performance interval claimed.

2 By PV Eni 55857 Viale Montegrappa 300, 59100 Prato, during the aspiration from manhole 3, after the three minutes provided, it was not possible to measure the flow rate because of the general conformation of the manhole (DEVIATION NR.2)

This deviation has no impact on the demonstration of the respect of the performance claim. The test results are in line with the performance interval claimed.

4.3. VERIFICATION RESULTS (VERIFIED PERFORMANCE CLA IM) 4.3.1. PERFORMANCE PARAMETERS According to the verified performance (Table 7) VRT system (models VRT - 219 l/h and model VRT - 650 l/h) provides the suction and the following depuration of rainwater in the manholes of fuel storage tanks installed by fuel stations, transport areas, private commercial activities and so on ensuring a maximal total hydrocarbons concentration at discharge of 5 mg/l and maximal total suspended solids concentration at discharge of 80 mg/l for both the models and a pump discharge flow rate of 219 ± 15%, 650 ± 15% respectively. This performance has been verified with the operational conditions specified in 4.3.2.

4.3.2 OPERATIONAL PARAMETERS The testing and verification activities were performed with different fuel-water emulsions simulating real events of pollutions in the manholes of fuel storage tanks (up to 5% of fuel). Mixture preparation will be carried out by Pozzoli Depurazione operators according to the instructions of the ACCREDIA certified EN ISO/IEC 17025 laboratory – “Tecnologie d’Impresa Srl” as described in Table 8.

A hydrocarbons concentration in volume within the oil separator >0,5% was ensured in order to simulate real conditions (oil separators stores the oil separated in previous treatments). Using a graduated rod and a reagent paste it was measured the thickness of separated oils within the sludge and oil separator. Through this thickness it was calculated the volume of separated oils contained in the separator.

Sludge and oil separator NEUTRAcom 3/300 has a cylindrical shape. To a thickness of 4 mm corresponds a percentage of oils that represents the 0,5% of the whole volume1. The measured thickness ensured hydrocarbons concentration in volume within the oil separator >0,5%.

Appropriate environmental conditions were ensured (T > 0 °C and no rainfalls) for the test performance . See the details in table 8

1 The internal diameter is 1200 mm. The distance between the bottom and the outlet of the separtator is 760 mm, so the maximum content of the separator is: 600 mm x 600 mm x π x 760 mm = 859514400 mm3 = 0,86 m3 The 0,5 % of the total content is 859514400 mm3 x 0,005 = 4297572 mm3. The correspondent thickness is: 4297572 mm3 / (600 mm x 600 mm x π) = 3,8 mm From this calculation we have chosen the value of 4 mm as thickness of separated oil that exceeds 0,5 % of total volume.

The test results confirm that VRT is suitable for the treatment of water with a percentage of hydrocarbons within the mixture up to 5 %. In case of higher percentage (e.g. in case of incidental fuel spreading) the removal must occur through cleaning truck services according with the local legislation.
