scholarly journals «St. Petesrburg Vodokanal» Experience in Developing Water Disposal Facilities as the Steps towards Transition to the Best Available Techniques

Author(s):  

The article presents the case study of wastewater disposal facilities development performed by the State Unitary Enterprise ‘Vodokanal of St. Petersburg’ which is regarded as one of the ‘green cases’ being implemented in the Russian Federation. It was emphasized that the Vodokanal of St. Petersburg ‘green case’ holds both sectoral and regional significance. Authors discuss approaches towards development and stage-by-stage implementation of reconstruction and modernization programs as to existing treatment facilities and for designing new ones. The implementation stages are considered from the standpoint of improving the environmental and technological policy of the enterprise. The implementation results for modern wastewater treatment techniques (mainly concerning nitrogen and phosphorus removal) are presented. The company’s experience on operating wastewater sludge incineration installations is described. The article demonstrates an urgent need for a detailed analysis of technological and economic risks and opportunities during strategic planning and designing St. Petersburg Water Supply and Disposal Scheme due to the transition to new BAT-based technological regulation in the field of environmental protection. The role of the best available techniques in fulfilling the requirements of the Convention on the Protection of the Marine Environment of the Baltic Sea Region (HELCOM) is emphasized. Authors describe technical solutions implemented by the State Unitary Enterprise ‘Vodokanal of St. Petersburg’ which allowed to remove the enterprise from HELCOM environmental «hot spots» list. Approaches towards further activities on sewage sludge and ash recycling are presented. The article formulates recommendations on improving BAT-related regulatory legal acts based on the results of the case study and notes the expediency for developing a national strategy in the field of using sewage sludge as a secondary resource.

Petroleum hydrocarbons, as aggressive components of diesel oils, after migration to the land environment can alter the activity and efficiency of ecosystems. They can also be dangerous to animal and human health. Eco-friendly methods for the reclamation of affected soils is necessary to manage degraded lands. One such method is the use of ashes. The aim of this research was to determine how soil pollution with diesel oil (brand name, Eco-Diesel) affects the chemical composition of maize (Zea mays L.) and whether the application of ash from a combined heat and power plant, as well as from sewage sludge incineration, could reduce the potentially adverse impact of diesel oil on plants. The research results demonstrated that soil contamination with Eco-Diesel oil modified the content of selected macronutrients in the analyzed crop plant. Eco-Diesel oil had a negative effect on maize yield. The highest diesel oil dose in a series without neutralizing substances had a positive effect on the accumulation of most elements, except nitrogen and sodium. Soil enrichment with ash differentiated the content of macronutrients, mainly nitrogen and phosphorus, in the aerial biomass of maize. The ashes increased the yield of maize and content of some macronutrients, mainly nitrogen but also calcium, the latter in a series where soil was treated with ash from sewage sludge thermal recycling. Both types of ash also resulted in a decrease in the plant content of phosphorus, while ash from hard coal caused a slight reduction in the content of potassium in maize. Ash of different origins can be an effective solution in the reclamation of degraded soils, which may then be used for growing energy crops.

The usually cheerful Insight Travel Guide to the Baltic States offers this synopsis of the Baltic situation:Their independence was sentenced to death by the Nazi–Soviet Pact [the secret 1939 Molotov–Ribbentrop Non-Aggression Pact] just before World War II. The pact envisaged the Baltic States would be parceled out between them, but it was overtaken by events with Hitler's invasion of the Soviet Union. The three states were incorporated into the Soviet Union in 1940 … Among few other people did the Soviet mill grind finer than in Estonia, Latvia and Lithuania … The final injustice was the permanent imposition of Soviet rule and Stalinist terror. Anyone a visitor meets today in the Baltics is likely to have a relation who was sent to Siberia or simply shot.

Agricultural production is one of the main sources of nitrogen and phosphorous inputs to the water bodies. Quantifying nutrient input from agriculture is needed both to develop effective environmental measures and to justify the technologies to be applied with due account for local natural and climatic conditions. Several related national studies have been conducted since 2015. Institute for Engineering and Environmental Problems in Agricultural Production (IEEP) methodology was used for this purpose. It determines the nitrogen and phosphorus content in the arable layer, including N and P amounts applied with mineral and organic fertilisers. Such factors as soil type and texture, the distance to the water bodies and the land use structure are used to estimate the nutrient input to the water bodies. In addition, the consistency of manure handling technologies with Best Available Techniques (BAT) principles is taken into account through introduction of relevant coefficients. Calculation results according to IEEP methodology were used in the follow-up general assessment of the nutrient load on the water bodies from different sources with the use of Institute of Limnology Load Model. Satisfactory correspondence between the assessment results and the values calculated using the monitoring data confirmed the adequacy of the above assessment procedure. Following its outcomes, the nutrient reduction potential of agricultural sources is approximately 10–20 %.

This article analyses the beginnings, development and prospect of Baltic studies in Romania. The article stands on three pillars. It starts with an investigation on the main sources of Romanian knowledge of the Baltic region and sorts out the way they have been represented in the Romanian mental images. Throughout the analysis, knowledge of each other is bonded to the concepts of memory and history based on the assumption that the largest part of our knowledge derives from remembering, this being applicable even in the high sphere of international relations. This theoretical framework is sampled to the case-study of Romania’s knowledge of Baltic area assessing the medieval, modern and 20th century legacy of the Romanian encounters with the Baltic States discovering that, although the distance between Suceava, the medieval capital of Moldova, and Vilnius is less than 1,000 km. (or 600 miles) and the Principality of Moldova of Stephen the Great neighbored the state of Jagiellonians, in most cases, the legacy of the relations between Romanians and Baltic nations played little role in feeding a sense of solidarity or complementarity between these nations. This pattern is now challenged by courses on Baltic and Nordic studies taught at Valahia University of Târgoviște and the activity of the Romanian Association for Baltic and Nordic Studies, which joins the efforts of scholars from various Romanian institutes and universities, especially from Iași, Cluj-Napoca, Bucharest, Constanța and Târgoviște. The analysis of these endeavors, the other two pillars of this article, brings forth educational, scholarly, editorial and dissemination efforts designed to change the perspective of the Romanian public in this respect.

Fracking has helped to usher in an era of energy abundance in the United States. This advanced drilling procedure has helped the nation to attain the status of the largest producer of crude oil and natural gas in the world, but some of its negative externalities, such as human-induced seismicity, can no longer be ignored. The occurrence of earthquakes in communities located at proximity to disposal wells with no prior history of seismicity has shocked residents and have caused damages to properties. It has evoked individuals’ resentment against the practice of injection of fracking’s wastewater under pressure into underground disposal wells. Though the oil and gas companies have denied the existence of a link between such a practice and earthquakes and the local and state governments have delayed their responses to the unforeseen seismic events, the issue has gained in prominence among researchers, affected community residents, and the media. This case study has offered a glimpse into the varied responses of stakeholders to human-induced seismicity in a small city in the state of Texas. It is evident from this case study that although individuals’ complaints and protests from a small community may not be successful in bringing about statewide changes in regulatory policies on disposal of fracking’s wastewater, they can add to the public pressure on the state government to do something to address the problem in a state that supports fracking.

Beginning in the early 1970s, Jewish and Muslim feminists, tackled “oral law”—Mishna and Talmud, in Judaism, and the parallel Hadith and Fiqh in Islam, and several analogous methodologies were devised. A parallel case study of maintenance and rebellion of wives —mezonoteha, moredet al ba?ala; nafaqa al-mar?a and nush?z—in classical Jewish and Islamic oral law demonstrates similarities in content and discourse. Differences between the two, however, were found in the application of oral law to daily life, as reflected in “responsa”—piskei halacha and fatwas. In modern times, as the state became more involved in regulating maintenance and disobedience, and Jewish law was backed for the first time in history by a state, state policy and implementation were influenced by the political system and socioeconomic circumstances of the country. Despite their similar origin in oral law, maintenance and rebellion have divergent relevance to modern Jews and Muslims.

Abstract Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings.

The provision of water services has traditionally been considered a responsibility of the state. During the late 1980s, the private sector emerged as a key actor in the provision of public services. Mexico City was no exception to this trend and public authorities awarded service contracts to four private consortia in 1993. Through consideration of this case study, two main questions arise: First, why do public authorities establish partnerships with the private sector? Second, what are the implications of these partnerships for water governance? This article focuses, on the one hand, on the conceptual debate of water as a public and/or private good, while identifying new trends and strategies carried out by private operators. On the other hand, it analyzes the role of the state and its relationships with other actors through a governance model characterized by partnerships and multilevel networks.Spanish La provisión del servicio del agua ha sido tradicionalmente considerada como una responsabilidad del Estado.
