Eficacia de la tasa retributiva como instrumento de control de vertimientos en Villavicencio

Abstract

The discharge fee for point-source effluents is one of the principal economic instruments through which Colombian environmental policy seeks to curb water pollution. This article assesses the effectiveness of this discharge-control mechanism in Villavicencio, within the jurisdiction of CORMACARENA. The research follows a method of analysis and synthesis, with a documentary and legal scope, disaggregating the fee into its normative dimension, its economic rationale, and its conditions of implementation, in order to determine whether the charge actually modifies the behavior of polluting agents. The review of the regulatory framework shows that the incentive to reduce pollution rests on the regional factor, which raises the cost of discharge when the load target set by the environmental authority is not met. The price signal reaches the regulated agent in weakened form, since the agent often does not know the tariff and perceives it as a penalty rather than a price; municipal sewerage service providers show widespread non-compliance; and pressure indicators on the water resource likewise fail to show sustained improvement. Verifying this at the local level required revenue, investment, and BOD5 and TSS load-compliance series from Cormacarena, which could not be obtained through official channels within the research timeframe. The study concludes that the discharge fee is legally sound and that its incentive design is coherent; what determines its effectiveness in protecting the water resource, however, is the manner in which the instrument is applied, not its virtues considered in the abstract.
