Implementation of the Baltic Sea Action Plan in Russia

LAND 19-2014

Summary of final report: Pilot Activity to minimize Pregolya River oil product pollution from Kaliningrad Port Oil Terminal

Background

• HELCOM Hot Spot#71
• Implemented by LLC TehnoTerra/Russia, supervised

by Pöyry Finland Oy and Finnish Environment Institute SYKE

• finalized in April 2014
• budget 123 000 EURO

Hot spot #71 - Kaliningrad port oil terminal

• The oil terminal is located on

the bank of a navigable canal in the estuary of the Pregolya River.

• The Kaliningrad Port Oil Terminal

(KPOT) is currently part of the Kaliningrad Marine Fishing Port.

• BASE focuses on developing

recommendations for remediation of oil-contaminated soil.

Objectives

www.tterra.ru +7(812)318-58-58

• Recommendations for fulfilling the

criteria for deletion of the site from the HELCOM Hot Spot list

• Preparation of a pre-feasibility

study, including a cost estimate for different remediation and pollution prevention measures

• Agreement on a realistic

environmental programme for the

• il terminal together

Main outcomes

www.tterra.ru +7(812)318-58-58

• In addition to building on previous projects and existing

information, new screening activities were performed to determine the level of oil contamination on the premises of the Kaliningrad Port Oil Terminal and the adjacent water area

• f the Pregolya River.

Main outcomes

www.tterra.ru +7(812)318-58-58

• A map of distribution of soil contamination with oil products

(depth and area) was created

• The thickness of the contaminated layer of the soil was

determined

• Sites of the highest thickness of the free oil product plume in

the soil were defined in order to design a remediation project

• f the territory
• The statutory and legal framework of the facility’s

environmental activities was also determined

Recommendations

www.tterra.ru +7(812)318-58-58

Based on the screening results, the following remediation

• ptions were selected to minimize discharge of oil into the

Pregolya River:

• to improve recovery of free oil phase by installing new oil

pumping wells along the pier that was found to be the critical area of oil leakage to the River

• in three of the four waste water discharge channels from the

site to the River the concentration of oil in water exceeds the maximum allowed concentration of 0,05 mg/l by 2 to 14 fold. Water treatment will be improved by implementing physical, chemical and biological treatment processes that aim to cut discharges of oil to the allowed level

Next steps i.e. what happens after BASE

• The final report will be presented to the Kaliningrad

Marine Fishing Port by TehnoTerra (April 2014)

• Should the Kaliningrad Marine Fishing Port (of which

the Kaliningrad Port Oil Terminal forms a part) implement the Environmental Management Plan fully, a more than 50-fold reduction in oil pollution from the oil terminal to the Pregolya River could be

• expected. This result would allow for the removal of

the site from the HELCOM Hot Spots list.

Sources and flow patterns of pharmaceuticals in St. Petersburg to the Baltic Sea

10

Sampling

• Pilot study in St. Petersburg
• Influent and effluent at Central, Northern and South-

Eastern WWTP

• Initially: Diclofenac (DCF) and Ethinylestradiol (EE2)
• Analysis of pharmaceutical sales stats:

low use of EE2 in SPb -> more diverse set of ~20 pharmaceuticals used more often + naturally produced human estrogens Estron (E1), Estradiol (E2) and Estriol (E3)

• Average concentration in the summer 355 ng/l

(2013, Central)

• Average concentration in the winter 510-550 ng/l

(2014, Central, Northern, South-Eastern)

• Upper limit for release of diclofenac from the city:

1,1 kg/d

• Annual load ~400 kgEstimated concentration in

the Neva: 5 ng/l

• Concentration sometimes higher in treated water

than in untreated wastewater (diclofenac released from process)

Results: diclofenac

• EE2 levels low: even if no treatment, estimated

concentration of EE2 into the Baltic Sea: 0,004 ng/l

• E1: ~40 kg/a in raw sewage, < 8kg in effluent
• E2 and E3 not detected: probably degraded before

entering WWTP

Results: hormones

• 18 other pharmaceutical substances
• Levels ranged from tens to hundreds ng/l
• Highest max levels: Cyprofloxacine (871 ng/l),

Ketoprofen (756 ng/l) and Enalapril (611 ng/l)

• Concentrations reduced significantly in effluent

(exception: Clarythromycin)

Results: other pharmaceuticals

• The data can be used to assess overall release of

pharmaceuticals on the basin scale

• The data can be used to develop better suited

technology for the WWTPs of St. Petersburg

• The samples (~100) are stored frozen at SRCES

and can be used for further analysis
