This news release is translated into English and Spanish. Please scroll to the end to view both.

The Humboldt County Department of Health & Human Services, Division of Environmental Health (DEH) announced the opening of the wet weather test period for the evaluation of proposed individual on-site wastewater treatment systems (OWTS). The effective opening date is Saturday, Jan. 14.

Under normal rainfall conditions, the test period will continue until April 1. The test period is subject to closure if adequate rainfall is not received for a significant period.

While not required in all geographic regions of the county, wet weather testing is required for proposed OWTS sites with soils of low permeability requiring percolation testing, and/or where the depth to seasonally high groundwater needs to be determined. Wet weather testing is mandatory in the Variance Prohibition Areas as described in the Humboldt County Onsite Wastewater Treatment System Regulation and Technical Manual.

All parties planning to subdivide land or to develop sites with individual OWTS should contact a registered civil engineer, geologist or other qualified professional to arrange for testing as early in the wet season as possible. For all sites, the test process will require no less than three weeks of monitoring. An early start is highly recommended to ensure completion of testing before the test period closes.

Notification of installation of wet weather monitoring wells must be submitted to DEH and fees paid within five days of installation.

For additional information regarding wet weather testing procedures, call DEH at 707-445-6215 or 800-963-9241.

Comienza el período de prueba de clima húmedo Sabado

El Departamento de Salud y Servicios Humanos del Condado de Humboldt, División de Salud Ambiental (DEH) anunció la apertura del período de prueba de clima húmedo, para la evaluación de las propuestas de diseño de sistemas de tratamiento de aguas residuales individuales (OWTS). La fecha de apertura efectiva es el 14 de enero. En condiciones de lluvia normales, el período de prueba continuaría hasta el 1 de abril. El período de prueba está sujeto a cierre si no hay suficiente durante un período significativo.

Si bien no se requiere en todas las regiones geográficas del condado, se requieren pruebas de clima húmedo, para los sitios que proponen la instalación de un OWTS en propiedades con suelos de baja permeabilidad; que requieren pruebas de percolación, y/o donde se necesita determinar la profundidad más alta del agua subterránea dependiendo de las estaciones. Las pruebas de clima húmedo son obligatorias en las Áreas de Prohibición de Variación como se describe en el Reglamento y Manual Técnico del Sistema de Tratamiento de Aguas Residuales In Situ del Condado de Humboldt.

Todos los interesados en subdividir un terreno o desarrollar sitios con OWTS deben comunicarse con un ingeniero civil registrado, geólogo u otro profesional calificado para ejercer las pruebas lo antes posible durante la temporada de lluvias. Para todos los sitios, el proceso de prueba requerirá no menos de tres semanas de monitoreo. Es altamente recomendado comenzar temprano para garantizar la finalización de las pruebas, antes de que finalice el período de prueba.

La notificación de instalación de pozos de monitoreo de clima húmedo debe enviarse a DEH, y las tarifas deben pagarse dentro de los cinco días posteriores a la instalación.

Para obtener información adicional sobre los procedimientos de prueba en clima húmedo, llame al DEH al 707-445-6215 o al 800-963-9241.
